[quote name='MadChedar0']I recommend Red Alert 3 at that price.
On another note, is there a way to have your retail (before it was steamed) RA3 validated on steam? I've tried inputting my cd key and no dice.[/QUOTE]
No.
[quote name='paintball745']simply put no only valve games can be store bought and have the cd keys registered on steam.[/QUOTE]
Incorrect. While it's true that the vast majority of games on Steam can't be activated using their retail CD keys, it's not true that "only valve games" feature retail + steam activation. Alpha Prime, Dark Messiah of Might & Magic, Dawn of War Soulstorm, Defense Grid (keys fom D2D), Football Manager 2009, GTI Racing, GTR Evolution, Lost Planet, NBA 2K9, Prey, RACE, RACE 07, Ragdoll Kung Fu, Red Orchestra, SiN Episodes: Emergence, Saint's Row 2, The Ship, STCC - The Game, and Worldwide Soccer Manager can all have their retail keys registered on Steam, and some of them require it.
