Although posting new ideas in these kinds of threads is useless 99% of the time...
1. Interesting "different" places like the Alberta giant potatoes, the moons of Salina, they labyrinthy pathways of the nomads reactor, would be made even more interesting if they were kind of central enough to have pvp fights happend there not all that rarely, instead of just and oddity on the side that you explore once and then never go there again.
2. It may keep exploring a but more interesting if some systems were map-able in your nav map, but not included in the interactive nav forum nav map.
