TF2 is one of very few FPS-type games that I like. The graphics are unusual and somewhat polygon-obvious considering their not-so-cartoony counterparts by the same artists. However, this game has an interesting storyline which you learn through videos and other out-of-game sources. They tried to make this game easy and fast to log in and jump in to playing as possible. It's great but has frequent hacker problems that are hard to report/get rid of, and the option menu for muting a mic spammer usually gets you killed because of how long it takes to navigate. Other than that, this game is a lot of fun especially when there are many games to jump in to!
I've played this game for a while, and I you are a fan of Online Shooters, than this will not disapoint, the overall gameplay is fantastic, the grafics feel like your watching a Pixar movie, cept your blowing the crap out of someones head, the storyline doesn't matter, its mainly 2 rival companys fighting against each other, music is fantastic if you love that retro jazz and funk music or whatever its called, and replayability is top notch, this may be one of the most addicting games I've played in a long time.
BTW, buy it on the PC, the Xbox and Playstation ones don't update, so that means no new weapons or stages for you!
