I never have played a Tron yet so don't know how that game is. But it depends on how much you like your IJ. I have sold mine 2 weeks ago and bought and Addams instead. I dont like IJ that much and it is my "oddball"
So i guess you have to think. How much do you like your IJ. Will you regret it? and what is the state of your machine, if maybe in the future you regret your choice of selling it will you get a machine just as good or is it mint
