Ok on a quick re-skim of the rules, its better than the beta version I read a couple years ago BUT
It’s essentially Shadow of the Demon Lord mashed together with Blades in the Dark without much insight into how the two sources of rules work. It ends up being kind of a mix of too-crunchy and too-loose.
There’s a lot (a LOT) of bookkeeping in this game even in the more freeformy section and the basic dice rolling action feels too barebones to give a good sense of individuality to each player character when they’re not in the mech. Whereas the mech combat is essentially a d20 miniatures minigame.
All this is to say that its one of the better comprehensive (meaning not a sad mecha jam game) mecha rpgs out there but I still don’t think there has been a good mecha rpg.
