I am a big fan of SFB (Star Fleet Battles). In fact, I was searching around in the SFB web site where I found the link for SEIV which effectively changed my life.
I have also played Silent Death, AeroSpace, and a few other less known boardgames. I even have a game called "Rebellion on Mars" or "Battle at Mars", something like that. It has hidden fleet movement around the solar system. When ships do fight is uses REAL Newtonian physics to move the ships.
i.e. your ship has a speed vector and your engines only adjust that vector as you move and apply thrust. The map then moves at the average of all the vectors. I played a few games of it solo, but it is not much fun playing solo against yourself using hidden fleets.
It was too complex for most other people to play. It was fun and used realistic physics for everything.
