The big pull of Elite is that we have THE G MILKY WAY to explore!
The base Discovery scanner and Detailed surface scanner are base ideas - more placeholders in my opinion and I would like to see 2.3 or 2.4 or even 3.0 (sod space legs lets have real gameplay! ;-)) have this expanded upon.
It's a sci fi universe, lets install quantum entangled resonators and let them provide deep core scans of bodies and create visually stunning views of these beige planets that abound this universe.
Lets have a way that players can share discoveries, or for the storyline arcs for Formadine, Guardians and Thargoids have some in game tools that help track down locations, or investigate sites with mor than just our lasers and loud honking ADS.
I think the number of systems that have been "discovered" is les than 0.0016% or something stupid, but in current gameplay there is no incentive to return to those systems.
Gameplay along lines of survey missions, new exploration equipment, different SRV types could be developed that incentivise players to not just jump,honk,jump, honk etc. But Jump, honk, analyse, select, investigate, and bookmark for return.
Just cos you have been to Sag A or Beagle point doesn't mean you are a great explorer, it just means that you can repeat a simple set of operations for a long time.
Discoveries can happen in our back yard, or discoveries occur on the shoulders of previous discoveries.
If you make exploration meaningful beyond just pointing at an object whilst a 30 sec timer counts down, you will get more player involvement, wider gameplay opportunities.
Combat has a plethora of weapon types and support modules and engineer enhancements that gets those that like combat all excited and frothy, i think is its time to widen the toolkit and let teh froth overflow on the exploration front.
Give players an opportunity to play Elite their own way, by enhancing th placeholder toolset that is here at the moment with stuff that will make the likes of DR Kaii and CMDR Nutter and even Obsidian Ant dribble in their sleep with anticipation.
In closing I would paraphrase a rabble rousing speech given to some fools in a field...
"I see you stand like greyhounds in the slips,
Straining upon the start. The game's afoot:
Follow your spirit, and upon this charge
Cry 'God for Frontier, Elite, and Saint Braben!"
I will shut up now I promise! ;-)
