This is $84 a year for the high-end subscription, including Steam discounts, which isn't really that much money. I don't know if the game is any good, but if you're the type of person that considers it to be, that is the sort of money that can be well worth playing for the feelings of accomplishment the game provides.

That's why games can have monthly costs that are similar to Netflix, with much less content - Netflix doesn't provide the same sort of sense of accomplishing something. (Let's ignore the fact that nothing in the game world might actually matter - it's the feeling that is important.)
