Me and a friend of mine have been working on a cyberpunk vs. steampunk game. It started as an RTS, then a FPS, RTT, and now out of our own technological simplicity a tabletop game

. I've been working units for the steam armies and I'm having some trouble with really steaming them up. I am trying to keep in the realm of realism but it seems as if you must sacrifice one for the other ( I had to add rayguns, which I was going to avoid, just to get weapons that looked steamy enough).I'm using modified units from here
