That's actually pretty much my own thoughts. There was a recent thread about finding undiscovered black holes and people were saying how most of them will have been found up to 1 or 2 thousand LY away. I'm more pessimistic and reckon that the vast majority with 5000 LY have already been tagged. On my current trip it took me about 10,000 LY before I was finding interesting systems (ie less common stars) that hadn't already been discovered - and it's not even as though I were heading towards anywhere special. And the next person who comes this way after I've handed in my data will find it that bit worse.I am not saying that FD should not keep a record of who visited what and when. They probably should and it should be available for players to read (i.e., the "history books"). I'm just saying the tags (seen via the system scan) should go. If the game devs want to encourage the sense of immersion and sense of discovery that exploration has to offer, then they should be removed because it's discouraging to new people, or so I imagine, to start exploring only to quickly learn that your visiting of a system is nothing new (and given the number of reps I have received for my comments on this topic, others seem to agree). Yes, there are 400 billion systems blah blah blah. But it is those relatively few systems a few hundred LYs around Known Space that actually matter as they are the systems that new players will be exploring first and the "400 billion systems" argument applies much less to them and only becomes more relevant the farther out you go. And the problem only gets worse with time. Just because something is currently in-game does not mean it has to stay in-game.
It's hard not to become jaded, but I still remember my first trip out of the bubble. I only got as far as the Coal Sack but it felt exciting. Dangerous. And there was a sudden urge to head back to safety. I then followed that up with what was going to be a trip to the Orion / Barnard's Loop complex but ended up as a tour of all the main nebulae to the 'south' of Sol. That was a real achievement. Those two trips were before the first discovered tags were implemented and whilst I knew that at least some of the systems would have been visited before, there was none of the "look, you're not the first and dozens have been here before you" being thrown in my face. I took a look after the tags were introduced and whilst I did get a few in the nebulae, most of those systems had been discovered before I got there. And by now they *all* have. Every single one. If I were starting again those trips wouldn't seem anything like so magical and I feel sorry for the newer players who won't get to experience what I did.
