Just get it! There are so many fun modes and maps. And it has a HUGE Brony fanbase (which offends some players, but its rare to find a player who hates FIM).
Haha. And if there is, just keep killing 'em. Thats what I do, if they dont have a mic.
Oh and protip: When searching for servers, look for ones with unusiam map names. These are most likely "party" servers with an infinate play mode and (usually) instant respawn.
Also a good tip since your a noob is to try out all classes and see what they do, what weapons they have, how fast they move, exc. And when you get a free random item in a drop, equip it and try it out! After awhile, your backpack will get full. Then I reccomend making a purchas at the store which will give you much more room.
I dont reccomend trading (unless its item for item) but if you do want to, beware of scammers. If something seems overpriced, it probably is.
And one final peice of advice. If you ever get a hat or misc in a random drop KEEP IT!!! They are VERY rare and expensive.
Ahem, this has been SB888's guide to TF2. You can friend me if you want. I'll give you some items. NLR_Captain_ThunderRage777. My logo is the NLR emblem.
Happy hunting!
