The leas popular one on my MSPFA "favourites" list is "Ringscape", a Sburb fan-session story. It starts on Earth C. Of the players revealed so far, 3 are Carapacians and 3 are Trolls. Always enjoy a bit of Carapacian rep. It may not be the most in-your-face-awesome comic out there, but it has neat artwork and an understated charm that I really enjoy. Sadly, last update was about a year ago.
