The audio on the TRON was a little lacking when first released but I believe a gamecode update fixed it and added alot more cool audio. That was the only gripe I have heard from a owner who got one of the first TRON release games. But TRON is a really striking colourful game with beautiful artwork, both cabinet and playfield.
I know this might sound funny, but the artwork on the playfield is very relaxing when u play the game. I am hoping STERN continues with the TRON so I can get one down the track if money permits. Variety is the spice of life. IF u liked the movie, TRON should be a good pick up.
