like where Rob is going,

I have often thought about the game safe cracker where it spits out a token, maybe as a unique thing is - once you achieve 4-5 missions and you get to the stage of a wizard mode a plastic token is spat out to the player / owner. The game still continues until you lose the game, but at a later stage that night , next day etc you get a one off chance of starting a new game at the completed 4-5 mission status but placing the token into a special dedicated slot and hit the start button and you get a game that starts at the advanced point to hopefully achieve more goals with more (3-5 ball game start) balls giving players a opportunity to see the depth of the game and make them want to strive for getting more missions finished.....

Maybe the gadegt could hold just 5 tokens so you can achieve them and extract them through playing and have a night of trying to achieve further goals = adds game variety but might need the score to start at zero so people are not achieving unfair high scores..???
