I think GOG & Steam and others should all honor legit game registration codes. Stalker soc code did work for me. I have a lot of games and I'm not sure I could find all the codes, but I could find many of them. I listed most of them (games) here on / in the forum someplace. It would be great to see more and more games added to the very sparse list. Just saying ...

Origin allows you to add any EA game with serial you own to it, and Steam also allows you to add quite a few retail codes to it, a few of which were non-Steam, though they migrated to it.

Yeah right, what a fecking shame!!

I hoped that with Stardock on board we will be able to use old Impulse keys for Stardock published games, but I am afraid that this initiative become a victim of its own popularity. I saw it being motion on several sites as a easy way of gaining a game by reusing one of many keys that are published on “warez” sites. Great initiative that did not survive contact with reality, shame on the people that simply are not able to play by the rules and need to bend them.

Are you sure? I thought it was Do-Re-Mi..

I'll sue them! I swear to GoG I'll sue them!

Where can one see that list?

Thanks.
Of course that list isn't that incredibly long, so I'm not sure what was refered to as "seven pages long list".
Well, I suppose if you divide that list into seven parts, it can take seven pages...

I have to press the "page down" button 7 times to get to the end of the page. maybe that's what he meant?
