I've owned Tron and still own WOZ. Tron was AWESOME, especially thematically and music wise, but got kind of old in a small collection. WoZ is still here and I still have MUCH to do. The ruleset goes so deep, that many modes are still really exciting since I don't do well enough to play them very often.
GOTG - not enough play time for me to judge.
My vote is WOZ!
