There are also some great 20mm terrain manufacturers. The best thing about this scale is that it works for Road Rage, Dark Future, Car Wars 5th Ed, Warlands as well as a few other systems, and with a small purchase from Twilight, the minis and vehicles are perfect for a Zombie Apocalypse game!
I'm in love with 20mm..... I just finished one of the Dark Future plastic bikes. I tried to paint Goose's bike (as did the person who owned the set before me) but it looked awful at this scale. I think the fade they did in the movie is too subtle to show up at this scale meaningfully. So I painted it like the Big Boppa, not too original either, but they will help make a great Op's force! I'll post pics when I have the other two painted as well. This week or next.
