Tron was on my wish list from the moment I wanted an arcade. I actually purchased a Tron many many years ago and when I was loading it up, it died. So I decided to back out of the deal and picked a different game the guy had in his garage (Cabal).
I really wanted a Smash TV in my arcade for a few reasons. 1) It can't be emulated that well because of the two joystick controls. 2) It's an awesome co-op game. 3) The PCB can be swapped out with Total Carnage (Smash TV II) 4) The sounds are so rad.
