I am violently opposed to mixing a fully compatable MHS (with some of my favorite Marvel Characters) into my HS games. There is no way that an HS Castle set would work for Castle Doom anyway. Expanding my game options and enjoyment is the last thing I want to do, so I'm gonna keep the two seperate, no matter how much fun I'll have mixing the two.

PS: Hey Ski, still organizing HS games in Dover? When do you play nowdays?
