Super Mario World Master Quest 6 is one of those fan-made ROM hacks that takes the original game and cranks up the chaos—in a good way. You still get the classic Mario platforming, but the levels are remixed with new layouts, tougher enemies, and some wild surprises. I remember jumping into the first level thinking it'd be a breeze, only to immediately get wrecked by a bunch of Hammer Bros. where they definitely shouldn't be.

The overworld map looks familiar at first glance, but dig a little deeper and you'll find secret exits leading to completely redesigned stages. Some feel like legit Nintendo-quality additions, while others... well, let's just say they test your patience. If you've played the original to death, this gives you a reason to dust off your SNES (or emulator) and actually sweat a little.

Fair warning: it's not for beginners. You'll need those cape feather skills on point.
