For me, this thread is all theoretical, because I (along with other GeForce Now users) cannot access the PTS. So, just as a reaction to what's been said:
1. Don't wipe the old scans. Just make them useless by re-randomizing post-Demeter ore placement. Reset the ground and the ore in the ground.
2. Definitely scale the ore obtainable with the "tax" on each tile, so folks are able to do what they want to do in the game.
3. Gradually phase in voxel/element obstruction, give us a roadmap to obstruction changes so that we can prepare, and be generous with what will be allowed. Otherwise, ships will become dictated solely by functionality rather than balanced with aesthetics.
4. Figure out a way to get input on proposed changes from people who access DU through GFN. Ideally, find a way for us to access the PTS.
