Zelda: Breath of the Wild.

I keep going back to it and trying to play it. Every single time I do I go "oh wow, this is such a well made game. Visually excellent in a way that will always look good, the interwoven mechanics are so cool and well implemented, love the open world" but I just really don't like it very much and inevitably turn it off after an hour or so.

RDR2 is similar, though I would disagree that it is a Good Game that is Good, so probably doesn't apply here.
