TF2 is crap because
1. You have to waste your hard earned dosh on items (such as guns, pointless)
2. Games can be annoying, such as your new and you join a medieval server. the demo's sword is so overpowered.
3. I prefer the xbox/ps3/vinilla version due to reason 2.
1. You don't HAVE to, it's not necessary.
2. This can be a problem, easy thing to do is to find a game, and expertiment on what classes you're good at.
Default weapons of classes are normally the best weapons.
3. Sometimes I play the vanilla version, sometimes I don't like it because its really explotiable. But other then that, the XBOX 360 version can/is good at times.
