Looking for a geolocation game engine

Please bare with me. I am a developer, and I know a fair bit about 3D, but I am a novice when it comes to games, so I might not always be using the right terminology. I am looking for an open-source geo-location/adventure game engine/designer software with the following properties, if such a thing exists: An interface that can be used by a designer (non programmer) to create the game: create a map, position items on it, set the various course of action the player can choose, etc. The player geo-location should be able to trigger events in the game; At each location, the player would be presented with multimedia material (a combination of text, images, video and/or audio track). User input should be possible to allow the player to answer riddles. Ideally, there should be some handles that would allow a developer to add more sophisticated parts to the game. Let's say that for a specific location I don't want to present a static element like an image or some text, but something more complex like a compass the player can use to help him find a hidden treasure, or buttons he has to press in a specific sequence to unlock something. The resulting game should be compatible with iOS and Android. Does such a thing exist?
