Is there a Stackexchange site where I can ask questions concerning:
Game design (non-computer games)
Gamification (e.g. within educational games)
References / studies which mechanisms make a game popular
Basic rules to consider in game design
I was thinking (depending on the exact question) maybe on the psychology site? Or for gamification within educational (math) games maybe on the mathematical education page?
Are there relevant sites that I miss? Or is there still a gap and there is not yet a suitable site?
