A game you "didn't know it was bad 'til people told you so"?
I'm talking about games that you still like but you had no idea were criticized so much.
The perfect example for me is Sonic Unleashed.
I admit that the game has its bad things, but I would have never imagined that it was so hated at the time... Although, that could be extended to the entire Sonic franchise, since for many years I was not aware at all of that "Sonic was never good", "Sonic had a rough transition to 3D" nonsense.
I genuinely enjoyed the game. Fans of the series claim that it destroyed the franchise. Perhaps they're right, but the franchise was pretty fucked up to begin with.
Then I pick Ultima 8. It felt like Crudader No Remorse but with fantasy trappings (because it didn't play like Ultima at all).
That said, it is janky, full of bugs and incomplete (clearly there was a second part that never came), but I had fun and at the time it felt edgy and kind of a dangerous and misterious travel.
