Hardcore-Story driven-Solo.
To me, hardcore just means you spend a lot of time gaming and you take it seriously as a hobby (or job if you're a YouTuber of streamer). I definitely do, I have my favorite series, and I love the discussions. I also make some YouTube videos - just small time though.
Metal Gear Solid is one of my favorite series, so obviously I am story-driven as a gamer. I really like just being able to sit back and think and really contemplate messages and life in general. To me, that is meaningful and satisfying.
Lastly, just as a more introverted person, I tend to prefer solo. I'm not against online necessarily, but I don't like how a lot of online focused games seem to sacrifice story and single-player. Not all do, but it seems pretty common to me.
