I love getting into an Eagle or Viper and blazing up and down the outside of orbis stations, twisting and turning through the support arms at speed.
I've often thought that an in-space-obstacle-course would be a great idea.
Maybe some future (x-games type) company create a massive assault course for pilots to blaze through at top speed. Cash prizes and mentions on Galnet for the fastest times.
ALSO:
I think we need a good mystery or conspiracy.
Something like
GTA 5's Mount Chilliad mystery. More than a year after the game's release, people are still trying to solve this elaborate puzzle. ED could incorporate some myth building with alien artifacts, alien cult factions, etc. I hope that when FD do finally introduce the Thargoids, its a carefully crafted and elaborate, plot-heavy story.
