An actual serious answer to the PVP question I've laid out elsewhere in this thread, but in summary: human opponents are all unique, even from engagement to engagement. They bring a creativity and variety that "bots" cannot replace.
Nearly all of the NPCs in Elite fight more-or-less identically to one another, with some pretty obvious variable-driven variety. They literally read your stick input and adjust to break aim, though if you reverski on them they'll stupidly follow, allowing easy shots. Two people can attack them and basically shut down their offensive capability as they get "stuck" trying to decide which to target, as their aggro continually resets. Basically, they aren't awful, but they're about as bad as typical flight sim AI, which means they are a far cry from a human opponent.
PVP encounters include everything from blowing up an E-rated Asp Explorer (or whatever) to full-on 15 minutes+ battles of attrition between equal opponents, where the one who makes the least mistakes will win. The encounters are frequently imbalanced in terms of skill and equipment, but actually dying to a PVP encounter - meaning, actually being able to kill someone before they get away - can be difficult once a player learns to build and fly their ship skillfully.
Uniquely to Elite - at least in my experience - is this attitude that PVP is "imposed" on players who just want to be left alone. I come from a combat flight sim background, as noted, and in those games, you attack whatever target you see, and if you can catch them unaware - and "bounce" them, killing them in a single pass - so much the better.
My understanding of the Elite universe, from the marketing materials, lead me to having the impression that it was more akin to a type of you-against-the-world "deathmatch" game than anything else. As in any game, you don't have to attack, but in Elite, the way the game presented itself was that you could be attacked anywhere, anytime - and vice versa.
And so I've played the game that way, and in fact my intention to play as a ganker was due to my desire to attack - and be attacked - as often as possible. So far, it's working out about how I expected, though I'll be honest that the strong hatred of this playstyle from some quarters has caught me a bit offguard. Thanks to this thread, I now better understand why that is the case, but I still do feel a bit of a disconnect from the viewpoint, if I'm being honest. It's not a lack of empathy, per se... because in fact, I know very well what it is to be ganked, and I have accepted that it will continue to happen to me as long as I play the game. It's more just a feeling that I'm accepting the game as it presents itself, rather than wishing it be something it isn't?
Of course, that last statement will anger people, and that is not my intention - it's more just my honest appraisal of the situation.
