My former-neighbor/pre-pandemic primary gaming opponent and I both own Gaslands Reloaded (I also have the original softcover). My former neighbor is pretty involved with WH 40k and, as a result, has really been working on building some amazing terrain for Gaslands. I think he’s already started making some cars.
I, on the other hand, bought a 11-pack (a 10-pack with a “bonus”) of die-cast cars for $9.99, selected specifically because of the 10 cars included, there were 3 each of 3 different colors along with 2 others that didn’t coordinate. I figured in a pinch, if someone came over unprepared, we could each grab three color coordinated cars (completely unmodified) and have a fun time with it.
Way back when I first got my 3d Printer and, around the same time, my softcover copy of Gaslands, I tried printing a set of dice. They didn’t turn out great but they are workable. A friend recently got an SLS 3D printer that could probably do a much better job (he said he bought it almost exclusively for custom dice and miniature models)
All-in-all, it reminds me of the wargaming ruleset my friends and I played a few times (over a decade ago when we were younger and had much more free time and much less free money) that used Lego figures for miniatures… only this time… it’s cars with guns (which bring a wonderful flood of memories of playing the old videogame Interstate '76)
