Someone else mentioned Habitica already, there are a few out there. I think they usually call it gamification. The only one I tried and was able to commit to was Walkscape (specifically gamifying getting out), although I’ve been slacking due to nasty winter weather.
My friend gifted it to me, otherwise I would have waited until the GOG release. Fantastic game, highly recommend. The story is so good so far, even if you haven’t played the first.
