One time I had a dream like that, except it was all being explained by Adam Sessler, and it was for the original GBA, so most of their stupid little skits involved me and my Mom in some kind of multiplayer mode struggling to get light on our screens.

It was called To the East, an RPG-ish game with a HUGE world map, worthy of MMO status, and there was this huge Dragon on the loose! :O You had to follow the dragon to various parts of the world until you caught up to it, and then would start the final battle with it. Depending on how quickly you caught it, where you forced it to go, and so such, the game's story would progress differently. The game's story could go on as long as the Dragon was still out there.
