Asimov has a short story I just read while backpacking in the mountains this past weekend. It's about humanity attempting to reverse entropy. The Last Question is probably my favorite short story ever.
Tagging onto this: there's tons of games to play that have regular tournaments. I run Warhammer 40k tournaments for my local store, and while you occasionally get tryhards that are less fun, the overwhelming majority of the community just feels like a bunch of people getting together to play plastic soldiers for a day. The new Disney game Lorcana is taking off, and there's tons of different tabletop games besides just board games to try at a local store!
