DidYouKnowGaming did a video recently detailing facts about the PS2 that were just discovered. I had no idea about any of them myself, did you? The first portion of the video talks about an unreleased Batman game that was being worked on by Volition. They got as far as making a demo of what the game would be like. It actually looked pretty decent, I would have loved to play that.
And good call on cutting the menstrual gags from MGS2. Pretty damn creepy to even consider having it in the game in the first place.
