I like the idea of a Steampunk style... lot of gizmos and stylized clothes, the invention touch also could bring nice gameplay, characters and assets...
Im loving the steampunk idea. Assuming that once we're done with the dm map (if thats what we do) there will be ots of assets left over that can be used in another game. It also lends very well to many different game styles.
Just like to hop in and say that I'm cool with almost all the ideas, eventhough i got some favourites.. Toy factory and steampunk! Don't really get why it's so important that the map a DM but that's someone else decision i guess.
