bzdursky: Alpha Protocol released on Steam yesterday if I'm not mistaken, but I don't know if it's barebones port or does it include GOG fixes as well. I'm not opposed to Steam release, but that's question for Capcom and not for GOG.
The Steam version is still the old version that initially released on Steam, it doesn't have the extra fixes that GOG implemented into the game, also doesn't have the other specials like Cloud Saves, Achievements etc that are only available on the GOG version.
Honestly, it's extremely fair if these versions don't release on Steam, GOG are the ones doing the legwork to get these released and working on newer hardware/OS's, if Capcom goes out of their way to do a Resident Evil collection like they have done for other old game series they make (Mega Man, Devil May Cry etc) then those are fair game for any and every platform in my eyes. Ultimately they want people to actually come to GOG and buy games if they release every piece of work they do on other platforms that's never going to happen, because why would anyone decide to buy something on GOG if anything they do will release on other platforms they there chained to so much so that they won't buy them on the store that made it happen in the first place.
