So in my mind I seperate this into ones that would have mass market appeal like Pokemon go, and ones I want to see.

Mass Market- Harvest Moon GO. Instead of collecting monsters you find materials and meet with other people. Basically picture harvest moon with AR. Seems like it would be easy to translate over to a real world map (maybe even a purged one). 

Me- Like a D&D version of pokemon go with Deep RPG gameplay. You could place epic dragons around the world with lots of creatures to battle to gain strenght. You would completely role play your character and you would group up with others to augement your weaknesses. There would be a guild system. Basically all the frills of a deep RPG game but in AR. 

Harvest Moon might work. Also maybe Ape Escape?

I saw an image (as a joke) of an AR Fatal Frame and I think it could work if properly done, taking pictures and seeing some ghosts, could be scary when playing at night!

Hentai games where u can touch their tits and do other stuff
