So, it's my guess that they'll release a third big box expansion, and another little box.
I came up with an idea that it would be nice if the next little box expansion was geared toward those who play with all expansions at once.
I sort of get the feeling, from a design point of view, that the expansions are mostly tested in isolation (might be wrong on that, but it's the impression from the sometimes less than eloquent way they go together, and the fact that the small and big boxes are made by different teams).
So, it would be neat to do something along the lines of "Munchkin Blender." A small box expansion that would help the game run better when playing with it all.
Ideas might be to:
introduce a different Ally-setup mechanic, so that you aren't having everyone but 11 of your over 22 allies leave town at the beginning of the game (actually, I think something like the Dark Pharaoh's rule might work)
add more Act Cards, so that they are actually a threat if you have a skyscraper mythos deck
Any other ideas? What do you think of this idea in general?
