I went with DS 2 because it's the one game that I played in full without being distracted by other games and it's the one I'm most looking forward to replaying at some point.
E 33 was a good game, but I don't fancy going through it again.
Oblivion (bugs aside) I enjoyed for a while, but the combat is a bit shit, even compared to Skyrim.
KCD 2 I also enjoyed for a while, but I became a bit sick of the mundane tasks, and time spent trying to find my next meal. I'll give this one another go though.
Silksong can choke on my plums. But in all seriousness, I haven't finished it yet - not even finished Act 1 yet tbh. Just got to some docks area. My biggest criticism so far isn't the difficulty, but the severe lack of checkpoints.
I suspect only GOY could change my current choice at this point.
