My bro rented Arkham Asylum and I played it for a good number of hours. Then I decided to buy the GOTY edition, and found out the saves don't transfer over—d'oh. So I'll restart sometime and then get through to the end. Really awesome game, and I'm pleased it was written by Paul Dini, and that they got Kevin Conroy, Mark Hamill, and Arleen Sorkin to voice their characters.
Since I've been on a Batman cartoon kick, I decided to buy some of Bruce Timm and Paul Dini's collaborative comic works, namely the Batman: Mad Love and Other Tales hardcover and the Batman: Harley and Ivy TPB. Really cool stuff, particularly the former's main story, which was made into an episode of Batman: TAS (well, technically The New Batman Adventures or Batman: Gotham Knights or whatever it's called).
