they should add in Two Face in this time round. its the reason why Batman had to fly off in such a hurry.
Adding Two Face would be a good move, but it shouldn't kick off with Batman confronting him immediatly after the last game, since it seems the sequel takes place some time later.
And they should obviously add Two Face because it's the second game.
A new Scarecrow confrontation could be easily done by having Bats suffer halluncinations of Scarecrow looking like some horrific, muscle-bound monster (due to fear gas or something). The fight could be a difficult one under the excuse that Batman's having difficulty fighting John "made of toothpicks" Crane because of the effects of the gas. Admittedly that doesn't sound as mind-screwy as the Scarecrow encounters of the first game, but I still think it's a neat idea. Perhaps they could throw in stuff like the terrain mutating to attack you, I dunno.
Penguin would be a decent boss fight if they took cues from The Batman and have him able to pull off crazy backflips and other kung-fu crap. Plus he's got a machine gun umbrella that allows him to fly.
People are flipping their [censored] in the Joystiq comments there. Which is ridiclous. Because someone else is voicing a secondary character in the game, the game is now ruined and is awful? Wha?
I think the previous actress did a good job, sure, but I don't really care that someone else is voicing some character in a game. If it doesn't ruin my ears, the job is done well enough for it to have served its purpose.
