Battlefield Bad Company 2(PS3):
-The Story stuff is not really hard to reach. Heck, you need to finish only the last mission on highest difficulty(Tough I did the whole game). It has the tipical mission trophies, collectables stuff etc. and kill trophies. As a game series known for it's Multiplayer, it also has online trophies. You mostly need time and bit of skills for them. I had troubles here and there, but the only Trophy I actually needed help where the 20 destruction kills. Unlike BFBC1 you don't even need all awards etc.

Call of Duty World at War(PS3):
-Luck. Again, if you try this platinum, remember those 4 letters: Luck. Because that's what you need. No skills ... okay mayby a bit, but mostly: Luck. This Game has no mercy and never heard that word before. But why? Veteran difficulty. Every COD gamer knows this difficulty, the hardest(Except BO3) difficulty. While later COD games usually where more mercyfull or surprisly easier, this one punished you. Your a player who throws the controller after dying 2 times on recruit? Then have fun paying hundreds of controllers just for this. Personally, Veteran here is more a trial & error then fair. Your dead with few shots, many areas have infinite soldiers, until reaching a specific point, checkpoints are sometimes too unfair placed and taking cover usually get greeted with 5+ grenades(Yes, I mean you pre-last mission -.-). The other stuff is with training good to do or is just finish this, destroy that etc. trophies. For the 3 coop trophies you might need other players for help, because the game is old, I had already trouble finding normally coop-rounds, and that was 2011. So as said again, you want platinum? Luck, good luck.

Killzone HD(PS3):
-Uhm, what to say. Personally only the higher difficulties have some tricky parts. Also need a second controller because Multiplayer is only splitscreen. And time, having to finish all missions with all 4 characters at least ones. I personally didn't found the platinum too hard, afterall it was my fastest platinum so far(6 days, 1 hour), could be faster if I played day and night.

Killzone 2(PS3):
-Luck. Again-wait, we had that already but it's true. Like COD WaW you need lot of luck. Heck, probably even more then in WaW if your not skilled like me. Finish every mission without death(Only in K3 and further they revive you), or finish the game on Elite are really tricky, especially the lesser one. Some missions are hard, others greatly unfair(Yes, I mean you Radec-Mission -.-). And if you think that is already horror, then have fun with the Multiplayer Trophies. Heck I reached(Unpatched) highest rank before winning 50 matches XD You also need to earn everything you can get in this MP. And some stuff is pretty hardcore. It's not for nothing the rarest platinum I have with only 2.69%. And by now the game has some age too, dunno how many are even playing online anymore. Well, luck, very good luck.

Killzone 3(PS3):
-Compared to the second game, K3 is way easier. It still has some annoying hard trophies, but Elite as far easier then in K2(Doesnt mean it's super easy tough, alone the last part where you fly was incredible unfair) and the online trophies are rather manual stuff(Revive as medic etc.). So yeah, if you want a Killzone platinum, preferale this one or K1.

Metal Gear Solid 2 Sons of Liberty HD(PS3):
-Oh dear, as a MGS-Fan I had quiet my trouble with this including bad memories back on PS2. A look at the list was enough to know why. Probably had give up if I didn't had a compentator in who get the platinums first XD Anyway yeah, back on PS2 I already played on Extreme to get all dog tags and extras and seeing to earn the blue wig made me gulp. Already the second torture back on PS2 took me 2 years(!!!) before surviving with like 1 stripe life. Also easier sounded then did, finishing all VR-Missions. Extreme and all VR Missions are hard, especially the several last ones. You will die. At my luck Extreme wasnt that hard like back on PS2, mostly because I had the experience and knew a few more tricks, like for Vamp. Still 20 bucking Metal Gears without checkpoint, good luck guys XD And have fun with the MGS1 Snake VR-Missions XD

Metal Gear Solid 3 Snake Eater HD(PS3):
-The legendary mission of Naked Snake, later known as Big Boss is for many fans still the best MGS games. And compared to the platinum trophies the easiest. Seriously the only hard stuff, if hard, a hitting all KEROTAN Play toy frogs and getting all animals, plants etc. in one run. The rest is easy, except for unusual MGS Players or people never played the game before. Tipp: The most difficult KEROTANS are the ones in te bike chase scenes.

Metal Gear Solid 4 Guns of the Patriots(PS3):
-People not knowing the game and looking trough the trophy list wonder why people say it's not easy. Mostly collectable stuff, should be easy, eh? But then there is one trophy, glimmering in gold for ... getting all iPod Songs? Why a gold trophy? Easy answer: Big Boss ... or rather say, the rank you need to get one of the songs. Still saying, it's sounds easy? Here is what you need for that rank, ahem:
-Playing on Extreme The Boss(Highest difficulty) Random: So? A bit harde-
-Finish in under 5 Hours Random: So, still possible, just-
-No Continue(If you die or fail, reload save) Random: O-Okay, that does sou-
-No Alarm(Red Alarm, the caution mode doesn't count) Random: I uhm...
-No Kills(Accidentally or not, exception Vamp and the beast forms and AI's) Random: Holy...
-No Heal objects like rations Random: I-I, there are sti-
-No special objects(Stealth-Suit, Bandana...) Random: .... buck
But yeah, the reast is rather easy when knowing the game. BTW, I had to do the run twice, because the first time, the trophy patch wasnt there yet XD

Metal Gear Solid Peace Walker(PS3):
-Hmmm ... it has quiet some hard trophies, like getting all S-Ranks ... but also easier stuff like collectables. Compared to the other ones I say around the difficulty level of MGS4. With a partner or three it can be easier. Nowadays tough look for partners, you barely find anyone online there anymore.

The Saboteur(PS3):
-A WW2 game that isn't a FPS-Shooter? Yeah, those exist too, it's even open world. The story itself has some hard parts, the rest is mostly destruction, destruction, destruction or collecting, collecting, collecting. One of the funniest trophies: Jump from the Eiffel Tower and survive. No, the game has no parachute ... but a little, tiny lake nearby to land Discord: Who needs logic, eh? XD

Uncharted Drake's Fortune(PS3):
-Funny thing is, compared to the trophy sites, U1 seems to be the easiest platinum of the first 3 games. I myself see it as the hardest tough. I found easy already hard at some points and Crushing doesn't make those easier. You need a lot of chillaxing if you not want to throw your controller. The rest is acceptable for trophies, mostly kill specific ones and treasure findings.

Uncharted 2 Among Thieves(PS3):
-With a trick U2 can be played with cheats without deactivate trphies as I heard. Itry staying fair and so I suffered my way trough crushing. Result: I would say it's a bit easier then the first game, but some missions, like the whole train ride or Lazarevic where just, gahh! The rest is like U1 mostly kill and treasure related trophies.

Uncharted 3 Drake's Deception(PS3):
-Nate's final adventure ... on PS3, has the same kind of trophies mostly. And crushing. Even tough it has the rarest platinum in lists it's in my eyes the easiest of the 3 PS3-Uncharted. I hadn't as many problems on crushing as in U1 or 2, mostly the last few missions in the dessert had some hard parts, especially the fire demons. Unlike bossfights in previous games, Talbot was mostly punching and pressing in the right moment triangle to counter. What makes it harder, compared to easier difficulties is, that during bigger enemy fights, you don't get showed which button to press. The ship was also annoying.

Metal Gear Solid 3 Snake Eater HD(PS Vita):
-The Vita version is slightly harder, mostly trough the smaller screen.

PlayStation All-Stars Battle Royale(PS Vita):
-Hard? Not at all. The only hard trophy I remember was an online trophy, the reast is easy. Probably the easiest platinum I have in my eyes.

Uncharted Golden Abyss(PS Vita):
-I have it with Uncharted, eh? The Vita-exclusive Uncharted has some random trophies ... I hate those. Unlike the 3 main games on PS3 I find this one better balanced on Crushing. I would put it from difficulty around U3, mayby even easier. Hard are the 2 "Screen-Swish" bossfights, because the ways to swish the screen are at some points completly ridicoulos or different then in previous difficulties. You also can pretty much not fail once or your done.

Battlefield 4(PS4):
-It's pretty hard ... if you get unlucky and get hit by a bug, that often kills your Singleplayer save. This seems avoidable by doing all Singleplayer Trophies without playing other games and the MP, so I did that ... and I got not hitted by it ... until I got all SP-Trophies and played MP. It has his hard moments, but I would say easier then BF3, besides, BF4 has no COOP crap(Otherwise I had BF3 platinum too). The MP trophies aren't really hard either, compared to BF3.

Battlefield Hardline(PS4):
-And another Battlefield. Hardline is rather easy, even on highest difficulty, if you use the right gadgets and sneak trough most of the game. Heck, I passed the last mission and only had to take out 3-4 guys at all. On Hard to say. Compared to it the MP that made it harder. Especially to get the specific shotgun to make the 25 kills is hard, but not impossible. It just takes time and skills and bit of luck.

Bully(PS4):
-Well, it's not really hard, rather time consuming. You dont even need to collect everything from some collectables.

Metal Gear Solid V The Phantom Pain(PS4):
-Mostly Time consuming, tough the S-Ranks and the chalenges in each mission can be hard, some challenges, mostly in the mission "Lingua Franca" are also pretty bugged.

Uncharted 4 A Thief's End(PS4):
-Drake's final adventure brings a rather easy platinum. As usually, crushing has some harder parts and one-two unfair parts(Yes, I mean you exploding mummies and mission 20 -.-). The rest is with tipps and training good to do or are just collectables/kill trophies mostly. I would say around U3/GA kind of difficulty. I did it without cheats, with them it's probably easier. The Speedrun is easy when knowing what and where to do already.
