If you reduce any game to its core loop, all of them are pretty simplistic. That's just what happens if you simplify things ad absurdum.
- Counter strike is just running around and shooting people
- BoTW is just walking around, killing monsters and replacing broken weapons
- Need for speed is just driving
- Factorio is just automating everything
And all these things are nothing but tasks.
That said, while this is pretty lame critique, that doesn't mean that every game is good and it also doesn't mean that every game is good for every player.
