I looked back a few pages and I am surprised that I didn't see curved blocks as a suggestion? Avorion's building system appears to be the best set up out of similar games to add curved blocks because of the scaling feature. In many other games curved blocks are relatively useless since you are stuck with a set radius for each block. With Avorion's system it seems that it would be possible to have a curved block set at any radius and could add quite a bit of complexity to builds as well as be one of the only games to successfully integrate curved blocks into the game.
