Son of Batman and Batman Vs. Robin are really, really good.

Batman: Bad Blood is just as good, if you don't mind a bunch of homosexual stuff with Kate Kane.

Batman: Gotham Knight is just... bad. Very poorly done.

Batman: The Killing Joke and Batman: Gotham by Gaslight are rated R, for those that care about that.

My brother and dad thought Batman Ninja was pretty bad, but I haven't seen it.

I don't know anything about the other 11.

@streamline: I watched the first couple minutes. The "old fashion way" is speculating, then once you've guessed they're dead, shooting an action figure of the character with nerf guns as many times as possible to make it fall over.

@naomha1 Actually, they got HL2 and HL2 Episode 1 and HL2 Episode 2 out in that time. And Portal and Portal 2 and others, technically.

@rey2 You should get this, then. Renegade was a lot of fun

@DarknautXXX That's Bach. Johann Sebastian Bach. He's a classical composer.
