Perhaps they just aren't as popular and thus get less exposure?
d20 Future is much better than I recall it ever being, now that I'm looking at it.
I don't think the genre matters that much. If you aren't specifically D&D/Pathfinder, you "aren't as popular".
There's also Numenera, and uh... not sure what else. I had trouble finding a really good fantasy/science fiction RPG, so I created/am creating one using the 13th Age rules.
