LOTR - Deep ruleset, good theme integration. Good playfield layout with nice toys integration. Very long games.
STTNG - Easy to get into but a challenge to master. Very good, if not the best film theme integration. Very good sound package with original voices of actors, cool! Very good playfield layout and complex subway system.
TRON - Very nice art package and great sound. Fast game with good flow. Not a deep ruleset. For me no long term pin.
