Don't forgetKatana314 said:If you're fine with the mac OS (my relatives have unfortunately found that from their viewpoint, it is much less intuitive than Windows) then I'd go for it. There will always be options for your games. A bunch of awesome ones I can recall (many indie, but no less awesome)
Killing Floor
Amnesia: Dark Descent
Team Fortress 2
Spiral Knights (no idea how it is, but it's apparently F2P on Steam)
SpaceChem
Portal 2
Left 4 Dead 1+2
Civ 5
Assassin's Creed 2
Trine
and others...
yeah I know this is from a decade ago
OT: Wait you have an Xbox and PS3 already? It's....okay. Well, if you have a gaming PC and PS3, you can pretty much cover almost all good games coming out. Exceptions being Halo, and Fable2, I guess. Seriously the Xbox has so few exclusives.
