so i got the orange box like two months ago, i've gotta say all source games are definitely awesome, plus the steam service is great in all that concerns online (buying included). i play TF2 quite a lot, portal doesn't have much of a replay value unless you want to beat a record.
HL2 and eps were awesome, though monotonous.
so anyway, any TF2 players? i've never been much of a multiplayer FPS guy (i mean, counter strike... i just don't get it...) but this game really does it for me. the whole class system is awesome, achievements and unlockables are excellent to get people playing and playing (i just got my first, the enhanced syringe gun for the medic), and the visual style is just so amazing, i'm love with it.
the whole advertising campaign with the "meet the" videos and the character personalities gives the game a lot more depth, even though in practice it's just some humour added to what could have simply been another war themed average multiplayer FPS as there are already many (and some source ones already).
anyway, cheers valve, i love your games.
