travel grind
Did you just try to coin that term or is this established - do we really consider travelling and the physicality of actual presence - not telepresence - a grind in a game that is literally about travelling through space in space ships?

Whish it was some (any!) other studio producing a space game, but Elite is still unmatched in scope and its positive qualities and I don't see any likely aspirants to even come close in the near future.
That's possibly the root cause of most of our woes: ED is still without competition (after the NMS disaster) so for anyone's open world realistically-scaled space flight fantasy there isn't really an alternative. If any of the big game studios decided to make a "GTA 5 in space" then that would create some real pressure on ED.
