I'm looking for something that will help me do airships and seige engines. Ideally the source would work ok-ish across versions (OSR, Pathfinder, 5ed). Basically a good vehicle thing with overland and combat rules.
Also, on VTT I've handed airships very awkwardly, usually making the PCs airship the center of the map and moving layers, making a huge token, or drawing and redrawing enemy airships. Sometimes I've run two maps at different scales. I'd just like something where, the next time I'm running and this happens, I have something that's coherent enough that the players can design and optimize and stuff.
Any suggestions?
Warriors of the Red Plante is OSR and has airship stats and rules, guess it wouldn't be too dificult to port them to PF & 5e.
