For the true mecha-boos out there... https://store.steampowered.com/app/1167450/DAEMON_X_MACHINA/ Has gotten really good reviews so far. Seems to be a spiritual successor to the Armored Core franchise. I would not expect an award winning story here, but it does look like lots of dumb fun. Best of all, has both PvP and PvE coop gameplay modes. I'm in no hurry to blow $60 on a new game right now, but figured it might be worth putting on people's radar.
