Mario's Nintendo Crisis by Exate
This is the part where I'd paste the quest database description, except there isn't one. This ois a quest from so long ago, it predates the database and exists only on a list of Exate's old quests. So uh... instead I'll just skip straight to Haylee's comments.
Mario quests have a... hilarious(?) history in the ZC community. You're either the funniest bad quest ever with the appropriately named "Mario Quest," the product-of-its-time comically violent Mario's Insane Rampage, or you're an experimental but unfortunately janky-due-to-the-engine platformer. Mario's Nintendo Crisis is perhaps the only formally grounded Mario Quest in ZC's history. It's got one of the sharpest aesthetics in any ZC quest, especially for its time (It's absolutely gorgeous for a 1.90 Quest.). The only real warnings I would give about the quest are that it can be pretty buggy (Some sections can result in softlock that can be escaped from by saving if you mess up.) and the difficulty curve for the quest can be quite rough. Blue Darknuts and Blue Lynels are in a surprising abundance in the earlygame, so there is a bit of a skill floor you kind of have to be at to enjoy the earlygame. After that, however, I think it's one of the most fun early quests and getting past that steep early game I feel is incredibly worth it.
Diving into 1.90 quests is always an adventure, especially ambitious ones. Who's ready for a blast to the past?
