SP only for me. Cannot concentrate on story with folks chattering in my ear.
I do like MP for other games that require less attention, like shooters or puzzlers or party games or sea of theives, etc. But anything with alot of dialogue? No.
Pretty much the same here.
I also don't really feel like playing a long-ass game measuring in tens or even hundreds of hours is ever going to be a good match for multiplayer sessions.
I'll probably attempt to have at least few MP sessions with a couple of friends just to mess around a bit for fun, but I don't see the regular scheduling required to achieve a full playthrough ever becoming a thing for me, not with all the other distractions in my daily life and how erratic my schedule can be.
