This is exactly what I was hoping for with GOG. I never sell any games, so I still own all the games I like. And while the price tag on games like Far Cry may be nice, I have no trouble playing them on my current machine. But some games need really big efforts to get running on XP or Vista and in the case of all the Tex Murphy games I haven't been able to get them running at all. With GOG that's not a problem any more. Install, play, have fun!
Under A Killing Moon was my first Tex Murphy game and after shit games like Phantasmagoria or TLC I was astounded at how good a so-called "Interactive Movie" could be. I came on 4 CDs, had great acting, tons of humorous dialogue, funny characters and so on. It's just great. The Pandora Directive is better, though ^_^
