Duffadash: I see no reason to remove Batman Vengeance (except that it sucks, but let's keep it for completeness sake) or Pool of Radiance (only the Infinity Engine games are owned by Atari to my knowledge).
Ubisoft no longer have the DC Batman licence so releasing previous Batman games while Eidos are making Arkham 2 would be problematic. Same reason with Pool of Radiance, not only is the licence now with Atari but Atari are in a legal fight with Wizards of the Coast. Legally Planescape: Torment should not be onsale by Interplay, in fact they deny all knowledge that it is.
Catshade: If those games appear on GOG, boycotting them would just give the wrong message to Ubisoft.
Agreed to a point. I still draw the line with playing $9.99 for some of the Ubisoft games on offer, they are simply not worth it. However games like B,G&E and Prince of Persia were instabuys.
