Actually even I have to point out this isn't exactly true.
- Planetside 2
- War Thunder
- Wargaming.net games (world of ....ships / tanks / warplanes)
- Battlefeild
- Battlefront
- EVE-Online
- Dreadnought
- Call of Duty
These are all great PvP games with strong communities and should be around for years to come.
But that is the key difference, they are PvP focused. Elite: Dangerous isn't.
Guess I should have defined it in terms of MMO(R)PG. Out of that list only Eve is remotely in that field, and even there majority of activity is PvE.
I did play Eve for some time and 99+% of my time was PvE, including and specially in nullspace as I was part of corporate support arm, mining stuff and so on.
