For Christmas I made some terrain for my brother who plays a tabletop strategy/vehicular combat game called
Gaslands. The game uses Hot Wheels cars as the base model so it gives players a massive library of themes and inexpensive models to choose from: race cars, futuristic cars, trucks, offroad vehicles, antique and muscle cars, TV/cinema models, etc. To give the vehicles a post-apocalyptic vibe, players root around in the bits leftover from previous projects (every model gamer has a bitz box) and add spikes, rams, guns, missile launchers, dead bodies, curb feelers, and any other kind of post-apocalyptic swag they can think of. My brother has a pretty good collection of vehicles already, so I grabbed this cardboard gas station for $5 from Five & Below and grubbed it up with some paint washes and added debris.
What the neighborhood petrol station looked like before peak oil and a zombie plague.
It was a one day project and I'm reasonably happy with the product, but in hindsight I've seen a bunch of places where I could improve it - heavier distressing at the bottom edges of the building, barbed wire along the parapet walls, more ballast and in different sizes, and definitely more grass tufts - I think they were the biggest overall improvement on the terrain piece and it would have looked better with at least twice as much on there. I was making my own tufts, though, which was a pain and that's another thing I learned: buy them pre-made next time.
I'd recommend
