The only parties I have ever understood or enjoyed are ones focused on a specific activity. E.g. a LAN party playing some game a group enjoys would be fun. Or playing cards or a board game or even a sports game if you're into that. Otherwise, what do you actually do?
So - what makes parties enjoyable for you? What do you think people that don't enjoy parties might be missing / should try doing differently at parties so that they also derive great joy from them?
Jokes, stories, laughter, insults, compliments, disagreements... those can be stimulating and rare experiences these days.
Sure, some of what you said is right - you can't play Xbox while you're at a party hanging out with people, and the opposite is true as well, you can't enjoy a party if you're off alone playing Xbox.
I'm an "all things in moderation, including moderation" type, so for me it's nice to occasionally explore the entire opportunity set available to me.
Plus, the social activity is good for your brain. We're built to interact and be social, at least to a certain degree.
Also drugs and booze can help a lot if you're at that stage of life!
I like being in loud spaces sometimes.

I like meeting new people. That's how you make new close friends.
> So you can't really have a proper conversation with anyone
I have had some very good conversations at parties. The only time I've really seen it be too loud to talk is when the focus is dancing.
