I know this setting is still in the works, but it is one of my favorite new settings that I found. With this there can be debris fields where battles have been fought, that can be easily mined for hull and other valuable things found in ships!
I think the minimum number of blocks should be somewhere between 5-10 blocks, and if there are less blocks than the minimum that are broken off, then the broken peice is simply destroyed, or (would be much harder to code) the small peices could attach themselves to other broken peices that are also small (like 10-15 blocks) so that there are still debris fields, but not a giant floating ball of debris which would be quite silly.
