FREE (Fully Realistic Exploratory Environment)
Basically, the concept of my game, which would probably spur its own genre, would be a game where you could enter the world and literally explore the entire area freely and do whatever you want. Imagine Grand Theft Auto, Pokemon, Dragon Quest and Zelda fused into one giant game, but without any restrictions, main objectives or ties to storyline. You, the player, create your own objectives and develop your own game on the fly. If you want to jump into a car and cause mayhem, you can do it. If you want to go off and save a random girl from a crazy axe wielding maniac, you can do it. If you just want to jump on a crotch rocket and ride into the sunset....you can do it.
