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.
A quick video showing some of the current blocks available in ScrumbleShip.

This isn't relevant anymore due to how much scrumble ship has changed, but I still want to point it out. Why is the size of the weapon = the size of an entire space suit?
That's still in the game, actually, so it's still a valid question : )
The spacesuits are compression-type spacesuits ( En.wikipedia.org ) and as such, shrink when they're not on a human.
Think spandex. Super spandex.
