Heh, I know people would pick on that half sentence when I wrote it... I almost removed it again but then left it in as a sort of bait

And the reaction actually proves my point...
I am not arguing that it doesn't make sense to to make a modernized software renderer (diversity is good as someone mentioned in this thread, even though in this case it is really focused on fringe uses like the Dreamcast homebrew scene etc.). And in any case, if the developer finds it interesting (or yes "fun") to work on such a software, who am I to question that?
What I am opposed to is the kind of circle jerk (yes another bait term

) many people around here and other places are indulged in. Self importance and demanding recognition (or otherwise stopping development) for projects that are (in the grander scheme of FOSS game development) at best "pet-projects" of those respective developers, will not get you much friends around the broader (e.g. more inclusive) internet communities like freegamedev.net.
The same goes for over the top copyleft/libre software advocates. No, we are not "hypocritical" FOSS evangelists, but rather those that look over the rim of our bathtub and realized that FOSS games/software can only have the intended impact if we reach a broader audience, and that those "extremists" are alienating that broader audience at an alarming rate.
