In the street fighter games, the Russian guy Zangief has one of the most powerful moves in the game, the Spinning Piledriver.

You perform this maneuver by doing a 360 on the controller and then pressing punch

But, that is kind of tough to get right, since when you press any of the 'Up' directions, your guy jumps, usually out of range of the move.

It turns out that you don't really need to go the full 360 degrees, just 270 will do

In fact, any 270 will do, so go nuts.

Also, this works with any move requiring 360s, including T. Hawk's crazy face-smashing move

And this applies to games in the whole series, including sequels and crossovers. Pretty much anything with the words 'Street Fighter' in the name.
