ScrumbleShip is the most accurate space combat simulation devised to date. Gather resources, construct a capital ship out of individual blocks, then pilot it with AI or human help against other players.

ScrumbleShip currently has a lot of ships, and displaying them all perfectly would take an incredible amount of resources. Thankfully, once you wander far enough away from a ship, it has a tendency to look more like a point of light than anything.
It used to be that for ships that were far enough away, I just drew them as points. This worked fine for smaller ships, but less well for big ships. So what I switched to instead was displaying ships based on their apparent size on the screen. I think this has made it a lot harder to notice that ships degrade into single voxels in the distance.
