A combination of the following factors:

- There's no real viable competitors on the market at the moment that are to my liking.
- I like my character's design.
- The dreaded 'sunk-cost fallacy'.
- I'm lucky enough to own a mansion in-game.
- I still harbour some hope that my issues with the game will be addressed at least to some extent.
- Friends and associates.
- The new PvP mode is pretty fun.
