All good games can get boring to you if you play them enough. Games I owned for a while and don't miss- MM, MB, SM, TZ, ST, and the list goes on and on. Great games, just played them so much that I wanted something new.
My Tron LE? Has been in my collection since I pulled it out of the box, and while I think about which pin I should sell to free up space, Tron gets talked about but the reality is I like it way too much to move it... even after all this time. I couldn't imagine going to my Pin collection and not having this one there, but that's me. Everyone has their favorite few!
