I'd have rather liked something along the lines of You can't Jump Straight to system without a Nav Beacon...
You have to take scanner measurements to a system without a beacon from 3 or 4 different systems spread out across different axis to get jump co-ordinates...then you can create an FSD jump...and place in a beacon in the new system...
It would have made the process of "pushing out" from the bubble slower...and created popular flyways linked by beacons that see traffic...and area's off the beaten track that explorers could revel in...
Also perhaps restricting the classes of stars that could be scooped from the entire main sequence down to a smaller sub-set would have made it more difficult to just push off on long missions...made route planning more complex..perhaps necessitated setting up intermediate fuel caches in orbit etc etc...
Yeah, that would have been neat, but that ship has sailed. I also got surprised that Universal Cartographics wouldn't have previously explored systems data for sale. When i started the game and found that i could purchase system data, i assumed it was previously explored/sold data, but not, it's just naturally available bubble systems.
For the scooping, i'm a bit disappointed that it's star based. I get that it's the handiest system as you appear near it, but gas giants would have seemed a more natural and less dangerous fit. It will come of course, but had it been there from the start, scooping stars could have been implemented as a desperate last resort.
