I like it mechanically, it's a bit thematically wonky though.
Yeah, I left out the flavor text. I figure you could rationalize it as plotting out the best wormholes and jump points. The map is abstract to some degree unless space is really this full of junk in the area.
I suppose I could read up on how big an area the game represents and the means of travel (warp, jumps, wormholes...etc)
