The 7th annual Mario Marathon started broadcasting live just a matter of hours ago, so go check it out. The fan-run event is a charity drive supporting Child's Play with a pretty fun set of rules: the group has a set of financial goals to be unlocked, each of which is linked to an in-game objective the players must complete. For example, the first $1 donated requires them to simply complete Level 1-1 of Super Mario Bros.; of course, as the goals go higher and higher, the levels and games required of the marathoners extend through Mario's history (as of this writing, the $8,062.37 donated requires a playthrough of everything through the Super Mario Galaxy 2 mission "Bowser Jr's Doomsday Machine").
What makes all of this particularly fun is that the marathon runs 24-7; the players aren't allowed to stop streaming until they've completed every last objective required of them — of course, this leads to some particularly hilarious time periods when the marathoners get stuck on brutally difficult levels. If you're curious, Mario Marathon has a handy checklist and FAQ that can answer some of your burning questions. Of particular merit is that every single cent made from the marathon goes straight to Child's Play, a charity helping children in the hospital live a little better through the power of playing video games.
