Stuff Like Devastation, Fall Of Cybertron Etc.
Basically true; Rise of the Dark Spark was a movie tie-in that didn't really continue the story of War and Fall. I know that ship has sailed, but I would have loved to see an actual Rise of Cybertron game.
The game was pretty hard generally. It's been ages since I last played it, but I could swear that it had fall damage in a platforming-heavy game, in addition to just having really beefy, hard hitting enemies.
