I've said before that I would love to explore the interior of my ship in Elite.
I no longer think like this.
Now, what does No Man's Sky have to do with this? Simple.
That game has pretty much aced "space legs". I mean it is amazing how well done exploring a planet on foot is. Brilliant job.
However...
All I could think about whilst finding animals and building bases was, I wished I were in my ship, flying.
I think that says a lot. Clearly, I didn't realise how much I love Elite's act of piloting until I experienced what I thought I wanted added.
I now am no longer worried about space legs in Elite. It is apparent that I play the game to be a pilot. And I'm happy with that.
What you're describing is called green pasture syndrome and is a perfectly natural phenomenon that when followed keeps things in life fresh and interesting.
For example:
Walking around and watching birds fly makes you wish you could fly around too.
Looking over your shoulder in the cockpit to see that door makes you wonder what's on the other side and makes you wish you could walk around and explore your ship.
Grinding rank killing NPCs in a CZ for days at time makes you long to just get away out to the black and just explore.
Crossing that 25,000 LY threshold out in the middle of nowhere makes you long for human contact back in the bubble.
Doing bulk trade runs or gathering mats ad nauseum (or any other monotonous peaceful grinding activity) makes you just want to blow something up.
Etc, etc, etc.
It's all part of a cycle of contrasting activities that any well made game needs in order to keep things fresh and maintain the feeling that there is always something "better" to do over the next horizon. If a game is designed well, you'll get this feeling several times a day. Space legs isn't the end nor "superior" activity, it's just one more endless horizon in the universe of Elite. Personally, I'm excited to see what's on the other side of that cockpit door.
