Peak Adventure Island. The NES game is known for being difficult to the point of being absolutely fucking broken by the time you reach its eighth world. I should know because I actually beat the stupid thing as a teenager before shelving it and never touching it again.

This game is basically what the NES original should've been. It's easy on the eyes (you even get to see Master Higgins make an ass of himself in little intermission cutscenes after finishing a world), has decent music and manages to be tough-but-fair instead of a tedious trial and error gauntlet. It's very doable on one continue, but it's worth noting that you get infinite credits. (No need to be aware of a stupid ass cheat that demands a prerequisite item to even work- Hudson really learned their lesson)

The controls still feel a little bit off, and that's really my only gripe. Higgins can still slip and slide on most terrain, but I will say the skateboard feels infinitely better to control than it did in any of the other games. Getting to the end of the stage with it also grants a big points bonus (which matters when it comes to racking up extends), and you will feel like a badass for doing so.

If you're going to play any Adventure Island, this is the one to go with. Super Adventure Island comes as a close second.
