Bally Midway's second Tron game went deep on the movie's sports-like combat sequences, combining the jai alai-like ring arena game with the disc combat seen elsewhere in the movie. The game was an ambitious experiment, projecting the gameplay onto a mirrored backdrop that added a sense of depth, and creating one of the first and most immersive 3D game environments in early 80s arcades. Discs of Tron's controls are one of the well-known challenges of MAME emulation, as the original game used a two-button flight stick (making it not ideal for the recently resurrected GRS Tron flight stick) and a push-pull spinner, but MAME is at least capable of emulating the projected backdrop effect in a satisfying way.
