aluicious: at fault? are they just being mean or something? those games (especially thief) would get a lot of sales here and sierra has not produced a game in how long? i hate world sometimes.
I don't actually know who owns the rights. I just quicky googled the game names, checked some wikipedia articles and drew conclusions from there. There are a bunch of Activision games on GOG already, so they're probably not all that "mean" about things like this. Often times the whole "who owns the rights to what" thing is a real mess with old games (or so I've heard).
They (whoever they are) are not really being mean, just minding their business interests in the way they see fit. Or not sure who owns what and afraid they'll get sued.
