Not sure if anyone has touched on this but I remember the ol' windows 95 days when I had a bunch of MS brand games, my favorite being the Madness titles especially Motocross madness & Monster truck madness. Id love to see these available on WP8!
Yeah, that all-too familiar feeling of nostagia....
Anyway, I'm not too sure if Microsoft sees any benefit of revamping old games for WP8 (there are tons of benefits), but maybe if enough users request this then those games might have a chance to see the daylight once again.
