I don't think this is very high up on the priority list, but I would like alternate pilots. So if I wanted a 2040 era pilot in a VF-1.. or a CF pilot in Skull leader. Actually now that I'm typing it, it seems sort of lame. But hey, while we're just throwing out ideas.
I would love some sort of ground crew / support vehicles (missile loaders, etc.) or diorama friendly items.
