Yep. The Animated Series is the first thing that comes to my mind when I think of Batman.

I finally got around to playing Arkham Asylum a couple weeks ago and I squealed with delight when Batman, Joker, and Harley Quinn all had the same voice actors from The Animated Series. It was great. Not only that, but the whole game was great, as was Arkham City which I played immediately after. Now I'm playing Arkham Origins which doesn't feel as great because Batman's voice actor is some other guy. ;__;
