Is there a way to play Munchkin Quest with 5 people without the expansion?

Question

Given that there are 2 extra colors on the color die, and you can buy the pawns separately, is there a way to play Munchkin Quest without the expansion?

I realize there are no stands for the monsters, but would any of the rules be affected?

Answer 1

There is a rulesheet for expansion here.
I took a glance on it, there are some special expansion-specific things, but I found nothing concerning gameplay changes, so I suppose you can buy (or make your own) munchkins and stands for the monsters of the appropriate colours and enjoy the game :-)
I can't recall any rule prohibiting it, and, as rules usually say, "Like we could stop you" ;-)
