I know quite a lot Sonic fans personally and one Megaman fan. From a, let's call it, research upon Sonic fans, they make sprite comics quite often because they're the most common Sonic fan stuff and thus seem easy to do. My thesis is: generally begginers will apply to produce the most common thing in community. And our most common is a JJ2 level. Battle or CTF (most often battle as a first level) for 1.23 and test or hotel for TSF.

If my thesis is true, then we can encourage people to do sprite comics by doing some on our own and putting them together in a highly visible place.
