While the game itself isn't out yet, we already have a pretty solid idea of what's in the game and what isn't. Only War has 12 specializations and 8 regiments pre-made, plus a regiment creation system. There's vehicles and gear and tasty enemy profiles. But what comes after the core rulebook? What do you guys want?
I would love to see additional rules get thrown into the regiment creation stuff. More specializations would be adored (Sabatorum Agent, Sniper, etc) and there are plenty of great regiments to add in (Valhallans and the Armageddon Steel Legion for sure). I've seen a lot of clamoring for Imperial Navy rules; at the very least, rules for a Valkyrie.
