While I can't really answer your question as I wonder that myself, I have noticed that there exists a surprisingly big amount of people that will just continue buying/pirating and playing games that they generally just hate and games in series that they have hated every game in for over a decade.

Sims and Pokemon have some of the biggest offenders in this from what I have seen. Like in the Sims 4 community you can see people complain and complain about how much they hate the latest expansion and how much the hate Sims 4 and how they are never playing Sims 4 again. And when the next expansion comes out they are there again same thing, just hate hate hate... but they keep playing.

Same in the Pokemon community some people haven't liked a singel game in the franchise sense the 90's but they keep playing and keep complaining over and over again with every new update.

This is such a wierd concept to me, why do you keep spending time and money on something that you dislike so much. Like I get buying a game and not like it and being disappointed it it, that'slife sometimes, but I really don't get buying/playing every game in a franchise or every expansion when you haven't liked it for years.
