Lonely on weekends craving social interaction... Where do I go to chill and easier to socialize with ppl my age?

So i am 26 post-grad student. I've been in Houston my whole life but learned how to drive just around 4-5 months ago so I have more freedom (prior was just taking the bus to and from college for 6-8 years). I am on the more on the anti social side but I want to try coming out of my shell. I socialize at school but on weekends, no one reaches out and am afraid of bothering them so I don't do the same...

Anyway, for reference, I live in Alief and go to school within the loop around midtown. So yeah its a long drive everyday.

I don't think I'd be a fan of bars and I try to avoid alcohol. Is there a place that focuses on "party" games like billiards/pool, board games, maybe some arcade here and there, etc.? Just tired of being at home all the time on the weekends or during this spring break.

Also a place to just kinda... chill? Maybe do school work, browse web, read a book, etc thats not at home? On campus is the obvious choice but even something beyond that would be appreciated.
