My friend was such a champion of this game. He barely slept for days when this game came out. He turned me onto it and I’ve been a big fan ever since. Unfortunately he passed away a little over 20 years ago. I know he would be rubbing this in everyone’s faces.
There’s also the GUN4IR project that can be put together for a fraction of the cost of the Sinden. The Sinden requires a visible border around your game.
