With the number of licenses increasing, I figure SJG has some of their own they could cross-reference...

Munchkin Car Wars. Cars can be vehicles/steeds similar to ships, and all the weapons can be enhancers.

Munchkin World Order: New Illuminates. Affiliations and such like Munchkin Impossible.

GUMPS - Greatest Unveiling of Munchkin Playing Since... seems rather obvious to me, but pretty much standard Munchkin but more maths and fiddly bits.

and more if I get back to this.
