A homebrew that I would like to see made is a two-player head-to-head version of Tron: Deadly Discs.
Have it be a three-on-three. One player-controlled and two computer-controlled warriors versus an identical number on the other side.
Have It be a best two out of three matches ala Street Fighter II.
Also, set it up so you can pick your proficiency level: Novice, Intermediate, Advanced, Expert.
That would determine what type of computer-controlled warriors your opponent has: Warriors, Leaders, Bulldogs, Guards.
That should make it is easier to introduce new players to the game by giving the vets a handicap.
Also, let the computer-controlled warriors respawn, but, of course, a round ends with the player-controlled warrior's defeat.
Another homebrew I would like to see created is Tron: Light Cycle Arena. Snafu is nice, but everybody really wants to play with light cycles.
Have them look a lot like the arcade version instead of the thick lines used in Snafu. Give the cycles three speeds: Slow, Normal and Fast. You might also limit the size of the tail created by the lightcycles before it dissipates or maybe give the player the ability to disable it.
That should create longer and more intense matches instead of ones that just last a few seconds. Best,
MC
