We've had several questions lately that we've been closing. What point-buy systems of magic (like psionics in 3e D&D) are there? , https://rpg.stackexchange.com/questions/14120/what-are-the-main-creative-commons-powered-tabletop-rpg-out-there, How do the rules that govern a Cleric's Turn Undead ability vary among D&D editions? (before it was scoped to D&D).
These all basically suffer from nothing more than the fact that the poster's a bit of a noob and doesn't realize that there are thousands of RPGs in every category ever thought of. Point buy magic, creative commons games, "turning undead" - it's like asking for "a good fantasy game!" RPGGeek has a list of, currently, 4007 different RPGs and 29,550 different RPG products.
I don't want to be unwelcoming by just shutting these down. How do we help people scope more tightly when they may not know exactly what they're looking for?
Because the questions have legit bases. "I want to design a point buy system of magic and so want to see some others" is a valid need, we just need a way we can answer it meaningfully in the format. Some of the others just need a lot more definition -but what if you don't have additional criteria? Maybe I don't care if it's transhumanist sci-fi or a D&D derivative, I just want to play a CC game so I can say I've done it.
Anyway, this is coming up a lot, and there's guidance specific to each question - but I can't help but think these are suffering from a similar root problem that we might be able to give meaningful guidance on in the FAQ or whatnot.
