Usually if I find a game boring, I stop playing it, but here I want to put games that I've finished even if I've found them boring:
- Pokémon Sword/Shield - I liked the pacing unitl the third city, then it become incredible boring and felt unfinished untile the very ending, that I think was entertaining, but overall one of my less appreciated Pokémon games ever.
- The Last of Us - As an Uncharted fan I was very excited to play this and I loved it, but I hated that half of the game or even more was just you slowly walk and hear dialogues between characters. I never played it a second time because of this, if they just had these moments in skippable cutscenes, I'd have played it much more because firefights were fun.
- Deadly Premonitions 1 & 2 - These are two of my favourites games ever, but from a gameplay perspective are absolutely terrible. The second one is a bit better, but still not fun at all to "play". Luckily, characters, atmosphere and story is enough to enjoy these masterpieces.
- Gears 4 (and Gears 5 too, but this one is a lot better IMHO) - As a Gears fan I still play all the games in the series, but the 4th was just terrible, with all these "arenas" full of robots. So boring, I've finished it, but I struggled so much.
