Well, in my wildest dreams I hope FDev would link exploration and combat gameplay (as they've linked trading and combat): Every once in a while there is a chance a derelict settlement or ruin isn't empty, but there are dangers lurking in the dark. Close to the bubble it could be criminals, smugglers, pirates, cultists; close to Thargoid space it could be Thargoids, close to Guardian space it could be Guardian AI/Constructs and in deep, deep space it could be unknown hostiles.
You could navigate and explore a ruin/settlement by working your way through and around obstacles (e.g. cutting your way through doors with a plasma torch or working the power generators to restore the power grid etc.). There could be traps/threats like automated defense turrets, unstable enviornment (a ceiling comes crashing down, a floor gives in). There could be loot/salvage/logs waiting as a "reward"...
I mean, there's plenty of stuff you could do with space legs and exploration, that is more than picking/scanning flowers and posing for screenshots
Yeah that sounds exciting but then I recall how clunky, boring, and perfunctory doing anything in an SRV is in Elite. So why would doing any of that on two legs be any different?
