Both of them Batman. I am pretty ****ing excited. And I got some Dark Knight Rises stickers and a Batman: Year One preview comic along with 'em awww yeahhhhh
I only follow Danger Club at the moment. There's so much history with all the big names that it's hard to follow on my current budget, I just like following something in it's infancy that doesn't require that I catch up on years of back issues.
I think Batman is probably the easiest to jump into. With all the others, there's always such a huge mythology, not to say that there isn't one with Batman, but it can be of a more episodic nature.
I don't like jumping in on the middle of anything regardless, it just feels weird to me. I also feel that if it's too episodic then you're just starting over at square one every time and you're just wasting your time. That's why I like Demon Knights and Nonplayer. Everything matters and you can't really miss anything without getting behind.
I didn't have much of an interest in comics until I got my hands on one of the Mass Effect comics. Not because the comics are good, but I never realized how great the artwork was for modern comics. Everything looks so crisp and awesome.
