Here’s an amazing list of hundreds of spaceship games. Compiled by Tom Granvold, it includes board, miniatures, dice, card and role playing games. If you like such things, check out it out.
Point of No Return is a set of free wargames rules for starship combat with simple vector movement and inertia.
Task Force Zeta is a set of free wargames rules for starship combat.
Pundits will tell you that representing space combat in 3 dimensions is a wasted exercise in mathematics, and that two ships fighting can be equally well represented on a 2-dimensional plane. What happens when you have three ships? ten? Did their captains all just conveniently forget about attacking/defending from the z axis?
Task Force Zeta allows you to fight battles against opponents in a representation of real (3-D) space using vector movement – without doing complex math every time you move or fire. Fourteen different ship classes are provided, along with fighters and bases, as well as basic rules for ship construction – design your own factions or convert ships from your favorite movies/TV shows!
