And let us not forget The Order of the Stick which inspired a lot of Dungeons & Dragons based comics in general; often using 'a compelling story with Dungeons & Dragons physics' as the premise. Even the fans have been putting this trope to use going as far as creating such comics in Burlew's stick-figure art style. A good example of this is the webcomic Anti-Heroes.
Similarly, xkcd has spawned a few more stick figure comics.
It's also becoming popular for non-stick-figure comics to go stick-figure for fillers. "Shirt Guy Xom" appears to be a Shout Out to "Shirt Guy Dom" (as GGC often riffs on Megatokyo)...which, in turn, was a Shout Out to "Shirt Guy Tom".
And somehow also inspired Last Res0rt, at least in terms of the art style. The main difference is that both Project Future and The Foxfire Chronicles use Cubi outright as a central locus; Last Res0rt, while having a few characters that appear Cubi-esque, considers these characters as a variant of Celeste, which have distinctly different powers and otherwise are very not-Cubi. (Also, evil.)
Fans from Nintendo Acres are known to duplicate the premise as well.
The Wotch is almost solely responsible for the creation of many, manyGender BenderTransformation Comics, some of which (or to others, all of them) are Fetish Fuel with very little in the way of actual plot besides men being randomly turned into very attractive women. The good ones don't exclusively revolve around it, with the victim(s) also having actual lives, problems and Character Development. The others are the exact opposite, in which Gender Bender is the center of the universe which everything in existence revolves around, particularly anyone male.
Parodied as a major running theme of Checkerboard Nightmare. Checkerboard Nightmare wants his webcomic to be a massive hit, so he constantly and shamelessly copies anything that catches his attention. Even his appearance and name were plagiarized from a guy he knew in school, Striped Reverie.
