The specific idea I had was for a three way Genius/Hunback/Promethean game, but I'd be open to any weird or cool connections of games, so long as there's a combining theme or inspiration. For example, the Genius/Hunchback/Promethean idea would be focused on a Frankenstein-esque story. Some more ideas off the top of my head: Leviathan/Beast - Monsters, even by WoD standards, who wear human skins. Changeling/Princess - Fairy tales aren't all their cracked up to be. Hunter/Geist - "Watchers on the wall" who work together to protect people. Janus/Geist - Formally normal guys who now have to deal with their "other guy," Incredible Hulk style. It'd take a lot of hashing out exactly which rules apply and which don't to ensure a smooth connection, especially for the less developed fan lines, but I think if we get some folks to put their heads together we can come up with a pretty cool setting. Check out the TV Tropes page for nWoD to see a pretty solid list of the gamelines and fanlines.
