I feel like a few people n the thread didn't read all the way through the OP's post.

The OP stated that they would quit the game now if it weren't for the fact that they had already paid for subscription and retainers that will last another 80 days. Someone replies that they may as well quit now if there's nothing else they're interested in now that the story plot points the OP was interested in have been resolved (whether anyone thinks those resolutions were done well or done poorly).

Then others come in and say "how dare you tell the OP to do what the OP wants to do! They will learn to like what's left in the game if they just keep playing". Seriously, the fanatical tribalism is out of hand.

There's an old saying that I think may have a lot of truth in the OP's situation. "Absence makes the heart grow fonder." The OP probably would be better off taking a break from the game for a bit rather than stay where they're now unhappy just because of Sunk Cost Fallacy. Maybe after a couple of months they'll decide there were other parts of the game they enjoyed enough that it's worth it to keep playing. Or maybe they'll decide that the story really was all they had been interested in and that there is no reason to come back. Either way, they're not on a one way street. They can go then come back later if they are interested.

The OP gets to decide whether or not they enjoy the game. We don't get to make that decision for them. It's okay for them to no longer enjoy the game even though they did in the past. It's okay to tell them it's okay to quit the game and play other games. And it will be okay if they decide to come back after.
