Just think: For all the time Drake has spent shooting dudes and climbing around in pursuit of riches, the answer was there all along: Make a video game about yourself.
Of course, then he would just be making a game about a guy making a video game about a guy making a video game about a guy making a video game ... and so on into infinity. The snake would eat itself and the universe would collapse from the weight the endless feedback loop of cause and effect.
So ... maybe he should just stick to the shooting dudes and climbing. Yeah. That's best.
