This is awesome, great work. Yep I have ideas.
Window frames, just attach them to buildings, they would have boarded up sections, bars, corrugated iron, different types. So one could have a relatively simple box building, but turn it into a wreck by adding these window sections.
Tattered curtains and battered up busted venetian/office blinds.
Like the floor overlays, but stuff for walls and ceilings.
posters and billboards, busted up and old.
fortification stuff, barbed wire, barricades of all types, stuff that goes on the top of walls to stop people scaling the wall etc. There is a million and one stuff for that kind of thing one could make, very useful is that for loads of games.
Floor sections with holes in them, no one has ever made these, but very useful, how one puts the segments together could make endless variations.
