Nice Buy Anton,
Have you ever played halflife 1 before??
Its a very good game, you don't have to have played it for halflife2(ep 0) then episode 1 and episode 2, but i would recommend reading a synopsis since its a very in depth game. You're gonna love the series, and the TF2 is great as well, however, its much harder on console. especially for engineers, But its still fun non the less. Portal, is amazing. I <3 the companion cube. A very fun experience.
