Pokemon Mystery Dungeon: Explorers of Darkness, Time, and Sky don't get the fame they deserve. Three of the most heart-wrenching games I've ever laid my eyes on. It has an amazing cast of characters that make you like them, a partner who isn't useless and helps you a lot, and most importantly, the character development. Oh my god, the character development is fantastic in this series. Bidoof goes from being a nervous rookie to still a rookie, but with much more confidence, Sunflora and Loudred go from hating each other to grudging respect, Drowzee goes from a selfish criminal to a person looking to purify himself of sin, you go from a weird and awkward outcast to a friendly teammate, your partner goes from a coward to a hero, Grovyle goes from one who has lost all hope to someone who is starting to think that good does exist, Dusknoir goes from a heartless coward who hated Grovyle to one of Grovyle's only friends, and you can even get the shopkeepers to go from teasing you to respect. You give a crap about ALL of the NPC's; even the ones that just pop up in town every now and then and you need someone to talk to. You really start to view everyone in the game as a person. You become emotionally attached to all of the characters, from the very bossy Chatot to that team that is constantly arguing over what to steal next, to that hawk that made buddies with a worm and is constantly hungry, to that monkey that gives sarcastic remarks and you're pretty sure he's doing some sort of drugs. The story is absolutely fantastic, some levels were so difficult I felt like throwing my DS at the wall, and some were surpisingly easy. The main story's final battle has some of the best music I've heard ever, and it's emotionally gruelling because of what'll happen if you succeed. There's an after-story too which ties up all loose ends. Note: For the after-story's final boss, bring an insomniascope.
Phoenix Wright should also be more famous. I swear this game's concept sounds stupid but underneath that it is a glorious masterpiece.
