Habitica: a role-playing game for self improvement

This seems to be something that would only be of use to people who get obsessed enough with RPGs that they're not going to, y'know, forget about them. I considered using it once, but I already know what would happen: I'd fail to turn checking Habitica into a habit, it would drop off my radar, and I'd be right back where I started.

(This also suggests another reason why the meta-self-improvement aspect works: the people who get involved in it are going to be the sort of people who don't easily forget about things like, well, Habitica itself, but do forget about other things. Such people will probably be interested enough in Habitica as a matter of course to want to improve it.)
