There's a reason the majority of comics I read these days comes from smaller publishers like Dark Horse, IDW, and Big Dog Ink, while from the Big Two, I really only still read Batman, Superman, Wonder Woman, Justice League, The Avengers, Spider-Man, and Iron Man, with the occasional book or however many from the series of other Justice League and Avengers members when something in those books about those characters connects one another. That reason is because if I want something that's off the beaten path in comics, I have to try the smaller publishers, because DC and Marvel have history of doing very poorly with stuff that's not about the characters that made them the Big Two.
Oh, sure, every now and again, something universe-spanning comes along, Blackest Night for example, and I just have to have every single book that has anything to do with it, regardless of what character's book the additional arc info is in, but again, that's coming down to sales of the books of the characters that made them who they are. I was excited for those fantasy and western comics DC tried putting out a while back, too, because it wasn't the same books I'd always been buying. I wasn't surprised when they were cancelled, though. I knew DC wasn't really trying. I like Injustice: Gods Among Us, though. Fun little comic adaptation of the game. Still, if we do get western, fantasy, or war versions of DC and Marvel's best-selling characters, I'd buy them.
