Ask HN: Would You Play This Mobile Game?

There's not a lot to say because you don't have a lot mechanically going on. It's a choose your own adventure but with an augmented reality backdrop? There doesn't seem to be room for player agency. It sounds like the players can only choose from a number of options, but you have to physically go places to make those choices.

The worst part of the idea, in my opinion, is required visits to specific locations, in my opinion. If they were something like "your office" or "any coffee shop", it would be easier to manage and destinations that more players would visit. By specifying that the game is localized around landmarks, you create so many problems. Now you have to define what the landmarks are yourself and manually place them. You have to do that for lots of cities if you want to facilitate a large userbase. You have to define choices and actions that make sense there. You have to test those locations and test that the actions there are possible. Then players need to go out of their way to visit those locations or remember to use your app while there. What about cities without specified locations? Can I play your game in Podunk, Idaho? That's more work for minimal, if any, gain.

I think you don't actually have an idea here. You need to think about this further. Would you really want to have to visit each of these places if you were a player? Would it be possible for you to become invested in someone else's story if it requires you go out of your way to participate? Can you explain the game to someone in less than 10 words? How do the decisions the player makes drive them to play further? What motivation does a player have to continue playing?
