For my group, I keep only Munchkin 2 and 3 with the original set.

Munchkin 4, 5, and 8 are their own pile which I dubbed "Munchkin Steeds". Not only does this make customizing mash-up games easier, but it allows adding steeds to other Munchkin games, something my group really enjoys.

Munchkin 6, 7, and 9 I keep separate since they add very specific game elements that are their own draw to be added to other games as requested. (Dungeons, Mash-up "Lubricant", and Dinosaurs)

I have a feeling Something Fishy is going to be very nautical based possibly adding Sharks and maybe even the Pirate Class to Fantasy, which will warrant its own separation like the Dinosaurs of 9.
