It's not just the playing, even the buying can be a chore, as you'll have to dig through dozens of different versions, DLC, and season passes to figure out what you are even buying, most of the time the actual online shop doesn't even tell you, you have to search around forums to figure out what you get. Starting one of those Ultimate Edition that includes everything also means spending 5min clicking though dozens of "You just bought DLC" notifications.

Getting late into a game series is also always "fun", as you can't even tell what is a prequel, sequel, spin-off or whatever, as most content no longer puts a number in the title. That's another trip to Wikipedia, as I have yet to see any online shop providing that information.

Needless to say, I stick mostly with older or indie games. I can't stand how every modern game needs to have skill trees, collectives, level ups and hundred different weapons that all look and feel the same.

That said, chores can also be quite subjective. The Riddler trophies in the Batman Arkham games can certainly be seen as chore when you just want to reach the end fast, collecting them takes around three times as long as the main game. I however found them to be the best part of those games, as they are very old school and based in exploration and puzzles, as opposed to just running from cutscene to cutscene. They give the player a lot of agency and freedom that is missing in the main plot.
