In case u havent heard of counter-strike(and u call ure self a gamer) it is a very good game pitting terrorists against counter-terrorists, it is an entirly online game that puts u in various differnet scenarious like:
Planting/defusing a bomb
Escorting/assasinating a vip
I'll be sure to include lots of screenshots so you get a good sense of the game.
