Simply put, I only explore because I have to go to a new system.
Exploration is stunningly boring for me.
People say "OOOOH look at the shiney new planets/moons/stars". Been there done that.
It just takes way too much time. Even in a well fitted AspX, going 1000 LY is painful. Boringly painful.
You can make all the back stories you want to about being 35K LY from Earth, but its just that, a story, a JPEG based story.
Mind you this is MY opinion and not that of some others, and I'm fine with that. But to me, Exploration is dull. As dull as mining.
When I say I get bored I get told "watch a movie while doing this" or "Read a book".
I play Elite when I don't want to read a book (I find TV and movies stunningly low intelligence, and try to avoid them, with some notable exceptions).
