The indie game equivalent are web comics. There are really well made and interesting ones out there, although finding them isn't always easy. For some, printed versions are also available.
There's a whole range of comics catering to those more esoteric (and often quite boring, frankly) storylines, and a good many of them have books for sale.
Check out Something Positive (terrible people), Stand Still, Stay Silent (kid friendly but a little dark, beautiful art), Dumbing of Age (ugh, but some people like it), Vattu (kid friendly, nice art, coming-of-age), Schlock Mercenary (goofy, sometimes a little mature but kid friendly), Gunnerkrigg Court (female protagonists), or any of several other dozens. All of those have books out, I believe, except for maybe SSSS.
EDIT:
Something Positive is probably the best-written webcomic out there today, with the best characters and dialog and plot--it's only flaw is that it might be a bit raw and inaccessible to people younger than teenagers (the first strip being a mean abortion joke probably doesn't help).
I think Dumbing of Age is targeted at people who are post-college, not kids. A lot of the humor and depth is most manifest to people who have gone through similar crap and can look back on it nostalgically.
Well, that's something of an edge case given that Erik Larsen originally came from DC & Marvel, so he has that over-the-top exaggerated anatomy style, but yeah it's indefensible.
Most of the newer Image stuff is really mature and has some fantastic female role models, see for example Lazarus, Shutter, or Copperhead, all have strong female leads.
I'm not familiar with Image anymore, but I remember Jim Lee's Wildcats and it was generally "supersexy females with ridiculous breast implants". And they had a couple more superhero teams, whose names I can't remember, which were similar to Wildcats in this regard.
