It's not even just stolen content, they're lazy with their physics as well. I've never seen such a sloppy job done with the sheer variety of engines in the LMH/DH classes, but they've managed to place the 9200+rpm Acura and the 7000rpm Glick to only have power and shifting at 8000 or so. And that's not even counting the similar aero parameters everyone seems to have, despite the lack of convergence like what F1 has.
