Those Lightsider interviews with Tom Veitch are interesting to read. The 1996 interview where he talks about the Lightsider game, especially:
Question: “Can you tell us anything about the Lightsider project? What is it?”
Veitch: "Lightsider is a short novel I wrote, that was originally supposed to be a Star Wars novel illustrated by Dave Dorman. In the process of writing this book I invented a game that Jedi play, using the Force, called “Lightsider”. The game turned out to be quite good, I think. After I had finished creating it, I realized that it would make an excellent computer game, sort of like Myst, but different in many significant ways. In fact I may have invented a new genre of computer games. So as we were negotiating a contract I asked Lucasfilm if they could put in a clause which would allow me a royalty of some kind if they ever decided to make a computer game out of Lightsider.
Well…it turned out I pushed their button on that one. They told me it would be impossible to agree to such a royalty, and that I was way out of line asking for one! They said they don’t do business that way – they acquire all rights when you do a project for them, and you are paid only for the original project. So I elected not to sell them Lightsider, because the gaming concept was just too strong. I am in the process of marketing it elsewhere right now. The curious thing, from my point of view, was the vehemence of their reaction to my request. They could have just said “no”, and that’s that. But it was as if I had poked a scorpion with a stick or something.
Ahh…but life is sweet, and it goes on forever. The power of the Force is great, my friends. Do not fear the Emperor. Do not tremble before the minions of the dark side. Realize the Lightside of the Force, live in the Force, and the Force will be your support and your strength, even in the face of great adversity. 😉 May the Force be with you!"
Has anything about the Lightsider game itself surfaced recently? https://starwars.fandom.com/wiki/Lightsider
Or is there anywhere that has more detailed information on the game?
