Well, Cary Woodham, I liked BOTH franchises as a kid and in both the IDW and Marvel comic books of those franchises, and even in the actual G1 Transformers cartoon (albeit on a more limited base than the comics), the Transformers and G.I. Joe universes combined, with the Decepticons and their allies siding up with COBRA and the Autobots and their allies siding with G. I. Joe. A Transformers Dynasty Warriors style game also would not be a bad idea, but if you have copies of both games, then you could unlock some bonus missions and be able to play those missions from multiple perspectives. I would also even extend more bonus missions to Action Man, Action Force, The Inhumanoids, M.A.S.K., and Jem (yes, believe it or not, but they ALL exist within the same universe).
