The problem is, says the game's producer, is that only one was really good. So 2K Games had three outcomes whacked and hardwired the upcoming game for just one conclusion. Sorry, alternate endings, it's just business.
Denby Grace, the game's senior producer, said the three dropped endings were just "OK", so don't lament their passing (Not the face, Tony. Not the face!) "We had four multiple endings at one point in the game, and then we looked at it and we had one really outstanding great ending to end our story," Grace told IncGamers. "We worked on these things and we have our players that focus test [the game]and we found that people were just replaying and ultimately only felt satisfied when they got to the one great ending."
Rather than fight it, the team figured if that was the ending most players would go for, the other three weren't much use. "We just said 'You know what? Let's just ditch these other endings, this is the ending everyone wants' and that's one thing we're happy with making that choice," he said.
