Todd Howard, Bethesda's executive producer, said Fallout 3 will feature over 200 endings:
Howard claims that the game itself is finished and has moved into the polish phase, but the team is adding several new elements to the game as they move forward.
"Being that we are Bethesda, everything gets a bit big, so as of last week we're over 200 endings. That's not an exaggeration," Howard said.
Small changes and additions to the ending, Howard explained, are multiplied by other factors influenced by the player's choices and decisions in the game, leading to over 200 possible ending combinations. Howard also clarified the game's scope and scale, noting that Fallout 3 ended up being much bigger than they originally anticipated.
"Fallout is probably twice the size that we originally had on paper," he noted. "We've definitely gone overboard... It won't end up being as big as Oblivion, but it's approaching that. The game is easily a hundred hours."
