It's hard to judge what can be considered an unpopular opinion because there's always gonna be at least a few people who share the same opinion as you, statistically. However, I guess I'll still share some opinions of mine that could be considered uncommon.
I think Prince of Persia is terrible. Almost every comment I've seen about the game praises it as a groundbreaking classic. Personally, I think the game controls like ass and the animation is the only thing worth giving a damn about. Also, I don't know if you can call this an unpopular opinion, but Mario 1 is my favorite of the original trilogy. Even though 2 and 3 are technically better and have more content, Mario 1 is just the most replayable to me. The amount of tricks you can pull off coupled with the fact that you don't have to sink too much time into it makes it the Mario game that I come back to the most. I could probably think of a bunch of other unpopular opinions, but I'm too lazy to do that right now.
