Evolution in technology has allowed Borderlands 2 to swell to about a "50-60%" larger game than the original, says Gearbox VP Steve Gibson.
"I wouldn't be surprised if it was about 50-60% bigger [than Borderlands 1]," he told GM. "But it's also so much denser. Heck, just the city of Sanctuary, something like that couldn't exist in the first game. Our technology has evolved a lot to enable us to do that now."
Despite impressive sales of the original Borderlands, the Gearbox VP said players don't have to have played the original to enjoy the sequel.
"A decision that was made at the very beginning of the game was that at no point at any time could someone in the story or design team ever assume that some person has played Borderlands 1. You just start it from scratch.
"There are cute winks at different things. For example, we have this thing where if you played the first one we detect your saved game and you get some cool unlocks."
