I read a Demigod preview in PC Gamer a few weeks back and it mentioned some of the units, though only The Rook was shown(big Babylonian-inspired dude with castles on his shoulders).
What would also be a good theme for a Demigod General or Assassin?
We definately need Pirate-Ship inspired General. You can't go wrong with pirates and pirate ships are even better. He can have sails and canons and a pirate crew visibly crawling over him.
