Finely steam = best program for games. i am glad to see sins is on steam budt alredy i am disepointet i candt activat my retailversion on steam meby its a good ideer to make that posbel (i know steam have to make some monny so meby a small fee wil be oke ) budt at the same time i have 480+ games on steam so i alredy spendt much monny....

why candt i activate my retail sins on steam............  

That is an opinion but I guess it is yours. I will admit that Steam has gotten better and the fact that Impulse is nonexistent means I will be buy more from it.

still its its disepointet u candt activate ur retail version of sins on steam like oter retail games ......
