even though these games are free, there just not that appealing. most of these free fps's are pretty low tech and want money for ridiculous reasons like clothing or something. And in order to be good you have to play ALOT to earn points to upgrade your guy and whatever, and they all seem to take after css. The only one that ive been playing and has been worth it is battlefield heroes because it is way different than your average cs remake. They got abilities, objectives, vehicles, and missions.
