um, there's an actual Transformers Video Game Discussion forum on this Transformers site. Moving this now...
It would be really difficult to make a Transformers RTS, as the RTS genre is about commanding armies at a time, and Transformers as a brand is about unique, individual characters. Something squad-based, tactical, or MOBA-like might work with that, but unless you think people are going to be into watching 12 Prowls fight 6 Soundwaves, it might not be a solid concept.
I think a Dota style Transformers game would be awesome. Team of 5 bots on each side with abilities, fighting to take over the other teams base. Sort of like tf earth wars, but with more abilities
