An examination of gravity in the Super Mario Bros series.
We determined that, generally speaking, the gravity in each Mario game, as game hardware has increased, is getting closer to the true value of gravity on earth of 9.8 m/s^2. However, gravity, even on the newest consoles, is still extreme.
In Super Mario 2, Mario experiences a g-force of 11 each time he falls from a ledge, a force that would cause mere humans to black out. In Madden 2006, the game's fastest cornerbacks can run the 40 in 2.6 seconds. (via waxy)
