I think I just don't really vibe with roleplaying in realtime with other humans, to be honest. I grew up trying to play tabletop RPGs (my dad was a DM and used D&D mechanics as a way to make storytime more engaging), but while I really enjoyed making up characters, I never had much fun actually doing a campaign.

The thing I love about computer games is that I can go through them at my own pace, pause whenever I like, hang around looking at a cool visual, go back to an old save and try something different, whatever. Multiplayer takes all that freedom away because everything has to progress on somebody else's timetable, which isn't as fun for me. Nowadays being expected to perform on a time limit just reminds me of work, which is the last thing I want when I'm playing a game.
