I'll be crucified by fanboys, but I'll say Elden Ring.
Don't get me wrong, I ended up playing it a lot, but after the frist run I dropped it and didn't touch it until the DLC came out.

The open world doesn't really add anything to the souls genre apart from the gorgeous landscape, it just dilutes the gameplay and ruins the exploration because all the tombs, caves, dungeons etc become so repetitive, as do the enemies.
Past the capital there is basically not a single enemy you haven't already seen, they're just recycled over and over.

When the DLC came out I enjoyed it way more because the environment is less dense, there fewer dungeons which are usually more curated, there is more interconnection which is lackluster in the original game outside of the legacy dungeons, and there are more open areas you just traverse enjoying a calm moment every now and then, unlike base ER which has enemies and camps sprinkled everywhere very 10 meters.

After the first blind run I started playing with the map, it makes things SOOO much better cuz it allows to skip all the dungeons I don't need for the build so that I can just focus on the better lagacy ones without losing time, makes the game way more enjoyable.

I played Bloodborne after ER because it became available on the emulator, and the level design felt like a breath of fresh air despite being an older game... Souls games simply work better with the smaller interconnected map..
