Quake II looks amazing with it's full RT version as does Minecraft. I'd love to see more games updated with full RT. My first thought was that games made on the Quake II engine would be the easiest to update. Heretic II, Sin, Soilder of Fortune, King Pin. Of course ownership of some of these IP might be disputed and they are hardly high profile titles.
