Just thought I'd quickly share an idea I had for a mobile augmented reality type game -- I have no plans in the short term to actually develop the game in question, so feel free to steal/change/do-anything-you-want with the idea -- just thought it was a cool idea that might be worth sharing.
Players would sign up from a website or via mobile apps, which would be available for iOS and Android devices, and game-play would be largely or entirely via the mobile apps.
The basic idea is that each player takes on the role of a paranormal investigator looking for signs of ghosts, spirits, alien activity, etc. These creatures and the signs they leave are not visible to normal human senses however, so the mobile app provides players with a set of tools -- special camera modes, EMF sensors, etc.
These would of course all be simple gimicky tricks, but we could for example provide a camera which "detects different, usually non-visible light spectrums", by accessing the phone's camera and then overlaying out own graphics on the resulting image. By accessing the GPS for location information we could put these in specific places, and players could track different sorts of "activity".
Awards could be given for things like being the first player to detect a certain activity, for getting additional different information about a previously discovered occurrence, or for discovering related activities. Players could also be given options to somehow deal with "hostile" presences, or to "help trapped spirits".
What does everyone think? Would this be a fun game? Would you play it? Can you think of any potential problems and possible solutions to them, or do you have extra ideas that could enhance such a game? Is anyone already working on such a game?
