Stuff that would make me reconsider Discovery/Exploration (I wouldn't do it for anything anymore right now, my brain simply can't handle this unprecedented level of boredom and robotic repitition)
- a Discovery Module holding recoverable/auto-returning probes/drones
Not unlike a Refinery, you enter the right screen, setup a few basic modes of Operation (Discover nearest targets, Discover furthest targets, Discovery selected Target only) and launch a number of Drones.
Number of Drones carried would vary in terms of Class and Rating of the Module.
After launching the drones, they'd Supercruise within scanning range (incl. Detail Surface scan) and auto-return to redock with the Ship to deliver the data.
Meanwhile, the Player would either setup his ship towards a central position within an Unexplored System and run it from there to optimize the Drone travel/return times - or manually send them out to i.e. very distant objects while scanning other (interesting) objects himself as usual.
That would greatly reduce the massive time needed to scan extremely spread-out System (which otherwise easily can take 60-90 Minutes alone).
- much more Stellar Phenomenon
Stars/planets that are still in the early aggregation phases of forming...
Vast debris/asteroid scatter fields that span the entire System...
Systems with obstacles requiring good piloting just to get through...
Systems with phenomenon that restrict visibility/scanner ranges...
Particle clouds with intense ionic/electical activity within system (stuff that you can't operate in too long without risking some damage - or simply get temporary System malfunctions when travelling through them)
Suns that burned out (Supernova)
Pulsars
Planets that suffered from massive Asteroid impacts (not round & clean anymore)
Comets
Planets that collided
Exoplanets that haul through a System after being torn away from their original Sun billions of years ago
[ continue as desired, the list of stuff missing out there - but that we know exists - is long... ]
Basically all the stuff that is not a few standard Suns and a few standard planets that all sit there, nice & clean, in a perfectly nice & clean (= sterile!) System.
I just don't think all Systems far out there are that sterile, nice & clean and Standard. Far from that.
There should be Systems out there that do not work that way (look & feel, but also travelling through them).
- stuff that surprises the Player
Really... anything.
Who says that Icy Planet #3 near that old gas giant or planet #5 from that burned-out sun was always icy? Who knows, things could have looked different 100 Million years ago.
Old abandoned stuctures
Signs of civiizations that either faded or moved along eons ago
Very old remains of Battles raging Millions of years ago
Long-defunc Probes/Drones sent out by other civilizations eons ago
Abandoned ships floating around through deep space
Hughe crashed capital ships on Planets - eon old desasters
Very active Planets that actually spew stuff into space (Volcanism shouldn't be only a Text string)
Tons of stuff I could imagine - the phantasy is your only limit.
Implementing 'jackpot discoveries' on random worlds should not be a major undertaking for FD to add to a future build. This would give incentive to the explorers who scan all the worlds in a system and not just the ones that look like they'll be high value.
