Octopath Traveler. The UI was terrible, the loot was nothing but stat sticks, and most of the dungeons, of which there were too many, were just long tree walk with potions at the leaves. Genuinely the worst game I've ever played. The three-directional sprites were also extremely lazy. I think I lost my mind right at the start when the lazy script response saw one of the characters' childhood friend suddenly develop amnesia and treat him like a stranger because everyone needs generic dialogue.

The music and cast of thousands worldbuilding was fantastic, but otherwise, I hated almost every single of the 80 hours I put into it trying to give ti a fair shake.
