I have a load of Mantic Deadzone scenery (some of it even built and painted
), as well as some cardboard scenery to keep me going.
I backed the BattleSystems SFII kickstarter, but that won't arrive before August. I also backed their post apoc scenery last year, so games may well happen in settings that look suspiciously 20/21st century - hey, it worked for Stargate
I also have a couple of starter sets of Sally Forth's
Terra Block terrain, so interiors should be okay for a while.
RPGNow has plenty of SF tile sets that you can print off if you're looking for spacehulk type games. I may even see if I can lay them over the Sally Forth MDF stuff to give it a bit of texture
