I'm planning on buying COD BO1 and COD WAW for the PC and already own COD BO2 The thing with COD BO2 is that it doesn't say "only dvd compatible" up the top of the case it has a PC symbol at the bottom so i was able to use this game through steam but with COD BO1 it has "only dvd compatible" up the top on the website i'm buying from, does this mean this game is not a steam version and i have to put my disc in every time i want to play it even after installing the game? if i do need to put my disc in every time i want to play it i will search for one that is a steam version and doesn't need the disc in to play it also i don't want to buy the games through steam i want to have the hard copy (i am aware that COD WAW is not able to be a steam game if i buy the disc as it was only made as a windows form but i can still add it to my library by adding it myself so i'm am not to worried about this game but would still like an answer)
