I stopped playing to wait for Mistlands in June 2021, but not before I had enjoyed playing it for 365 hours. I played solo and so the hype or popularity meant nothing to me.
Once Mistlands drops, I'll be sure to jump right back in again. I'll do the same for the next biome after that and so on until they release the game conclusion.
So, depending on your gaming routine, I'd say you'd get a few months at least of enjoyment from it. Or you could continue playing for the fun of it, especially if you're into creative building as many do.
