Apparently, at 5pm Central Time today, a 72-hour Pokemon game marathon is going to start. The goal is to catch every Pokemon from Bulbasaur to Darkrai with no outside trading.
They will be playing Ruby, Sapphire, Fire Red, Leaf Green, Diamond, Pearl, Colosseum, XD: Gale of Darkess, Ranger 2, and My Pokemon Ranch throughout this marathon, two games at a time.
copypasta from /v/, just wanted to spread the word.
