Do you want a "rank and flank" game with formations? Or are you fine with large "skirmish" games? Hobgoblins, Dragon Rampant and Warlords of Erehwon might be up your alley, since they can be customized rather easily.

DBA and its derivates are a bit more complicated as far as i know and are thus maybe not beginner friendly, though i do not have personal experience with it.

Nice work, i love that oldhammer look of the squig!

I already had the rules for a pretty long time, but i simply did not test it out. It is very high on my list though.

Haven't had much time to play recently, but i am working on 15mm minis and vehicles for Bolt Action and i plan to try out Chain of Command and Nuts sooner or later.
