Chess gets pretty boring because it's one of those games that can be solved. It's at its most fun when you have two players of relatively low and equal skill. After that every game kind of boils down to doing the same thing over and over again and you gotta start doing chess variants.
I mean, maybe the super GMs like Magnus can complain about memorizing certain opening lines to some outrageous degree, but even they still have competitive games. For the remaining 99.99999% of players like us, it's not even close enough to solved to be an issue, imo.
