The game is almost finished, it's just that the last couple of years have been a mess: people voted for an extension over the basic 1.0 plan I had, and not only it took longer than I expected to implement most of it, I also kept having health issues which slowed things down. Scope/feature creep hasn't helped either. XD
In theory, we should be a few months away from completing the game. I'll try to be more aggressive in trimming down my plans for the game, but I have been wrong several times before, so calling a date now feels wrong.
Also, it's worth noting that the main questline is complete, and you can already "finish the game", so to speak.
