Papers, please, and that dragon, cancer are both types of games that did not exist before. Probably there's a few more indie games that I am not aware of. If you want to stick to mainstream games only, even then there is real innovation. E.g. calling Super Mario Odyssee a rehashing of Mario Galaxy does it a misservice (in my view).
