Kraker2k said: I've never really played BMW, but is it just TM characters in a SRW like game, paying homage to and parodying various mecha series?
It's all that and a bag of chips, but the mecha references are mostly secondary as far as attacks go. Most of the techniques are based off of attacks used in the TM games, like Shiki's Seventeen Dissection or Archer's Unlimited Blade Works. It's when they have to fill in the blanks a bit that the mecha references tend to come out, like Sacchin using the Bakunetsu God Finger from G Gundam.
