This idea...
Is so ridiculously awesome that I'm pissed off that I didn't think of it first. Steampunk Transformers?! That's like multiplying win by win!
I hope for more. It's such an awesome concept that I hope you run with it. I could see a transformer locomotive, transformer dirigible, and a transformer WW1-style tank (a decepticon, maybe?) This is one idea with a huge potential for concepts.
