Right now I plan to assemble them and see what they need. The top halves will not be glued on, so that I can have fights in the houses, and I haven't figured out what to use yet for floors. The top halves will also be transparent.
I also need to figure out some sort of door, or at least teleport/door/two-fingered palmreader for the bottoms of the buildings.
I plan on spraying the whole lot silver when I'm done, then weathering it and adding hopefully fairly generic basing.
All this and I just found out I'll be doing overtime at work this week.
