I agree with the above mostly for Sins of a Solar Empire and Last Remnant, the other games suggested are good too.
For Steam, it depends of the games. If you buy a retail COD4 game, you wont be able to add it in your steam account but you can place a shortcut in your steam game window. But if you buy a retail version of Counter Strike, you need to add it into your steam account in order to instal it.
I suggest you:
Unreal Tournament 3,
Call of Duty 4,
Left 4 Dead,
Team Fortress 2,
Counter Strike Source,
FEAR2,
Portal,
Mass Effect,
Fallout 3,
Command & Conquer: Red Alert 3
