Mario 3 and Mario World both sit in the top 1% of all-time great platformers. I'm always up in the air about which is the better of the two, and the one thing that squeaks Mario World by is its save feature.
I've beaten Mario 3 dozens of times. I've played through every level at least once, but I've never gone straight through the entire thing without using a warp whistle.
Am I completely off base on the time commitment that must take. My guess is at least three hours... and that's if you know what you're doing. Too high? Too low?
Who here has played through the entire thing without being a filthy cheater? How long'd it take you? Did you beat it in one sitting or use the ol' overnight extendo-pause technique?
