That said, I'd be careful saying the sub can't be "trusted." It's annoying but when you do get an answer it's generally sourced and credible. As opposed to the unadulterated bullshit I've seen on the rest of the site regarding basically anything I have professional experience and/or formal training in.
The strictest moderation there is can be found in high quality academic publishing. You are allowed to publish only if what you say has high value, and is said in the proper way. Can't get your Flat Earth Quarterly published in Nature, and we're all better for it.
EDIT: Also, the way I make Reddit useful to me is I change the default sorting for subreddits from Hot to Top > Monthly, and also disable content recommendations. It'll shows less content and Reddit will sometimes say "No more content right now", which is great.
I swear some of the things I've been downvoted for in r/embedded is just out of control nuts.
So the hobbies/games I'm currently playing are subreddits I subscribe to and actively browse. Games like Anno 1800, Cities Skylines, and Manor Lords. All 3 have very active and passionate community members that are constantly posting high quality content around inspiration for builds, tips and tricks, community update news, patch discussions, mods, etc. etc.
If you want more silly subreddits not related to hobbies, it depends on what your humor is. Here is a wide range of options: r/AnimalsBeingBros, r/ActLikeYouBelong, r/softwaregore, r/raspberry_pi, r/lockpicking, r/FellowKids, r/dogswithjobs, r/BirdsArentReal, r/BreadStapledToTrees - subreddits that are related around hobbies or niche humor will make you love reddit.
Again, tl;dr, reddit is not the place for real life news. If you don't use it for that, you'll find yourself enjoying the website a ton more.
