I was doing star wars in 32mm with the legion models, but I gave up and sold them all, instead getting a lot 3d printed in 15mm. 15mm is perfect for sci fi.
Nice video. A few rule systems i have to check out. Far too little 15mm scifi, love the scale for company size games. Most of my 15mm scifi stuff is Wakes emporium, scaled up from 6mm
