The news that GTA V will be bigger than Red Dead Redemption, San Andreas, and GTA IV combined is impressive. It makes on think back to the vast expanses of GTA III, the game that pioneered huge open-world experiences. People spent weeks on that game, trying to complete every last side quest and find every package. In the vaults of the Speed Demos Archive, John "Silmaranza" Breedon shows off how he managed to do that feat in 6.5 hours. The whole thing took about a year to do but is impressive nonetheless. Who knows how long GTA V will be? It'll be a challenge for the speedrunners of the world, that's for sure.
