I really tried to give DC's 52 a chance. I really did, but I just couldn't get into it. Batman was about as close to what interests me, and I found the new Detective Comics fairly bland. Yes, they were a bunch of first issues and quitting on the first issue is ridiculous, but still.
I say that to say that if I can't get into the comics, I can't see myself getting into the game unless a bunch of people I know personally give it rave reviews. Which is really the only way I even tried Arkham Asylum.
So ... yeah, even without a monthly subscription I can't say it intrigues me enough.
