"Mega Man 2" is one of my favorite games of all time. Although maddeningly difficult, I kept coming back to it time after time to get my ass whipped, and loved every blade throwing minute of it. Naturally, I peed a little when I saw this video of the game re-imagined in '2.5D,' "Paper Mario" style.
Unfortunately, like all wonderful dreams, this isn't 'real' in the playable sense, but fans of the series can appreciate how faithful it is to the game. I even had a minor Pavlovian sweat response at the part with the disappearing blocks.
