Anything in particular besides sports shows you're looking for? I'm not an expert on that front, but I can at least recommend Haikyuu and Yowamushi Pedal as worth investigating (I'm assuming you've already seen Yuasa's Ping Pong). Haikyuu in particular should satisfy you on the character front.
Off the top of my head, I still haven't watched any space operas. I'd rather avoid long-running shows if possible, but would give one a try if it's good enough (which I believe most don't, since long-running series tend to get stale in order to drag the story out as much as possible).
Please watch Haikyuu!! and Ace of Diamond.
Watch Haikyuu and Yowapeda
Guess I'll check Haikyuu out later, then. I'm actually not as interested in the show being about sports per se, just a narrative that's character-driven. I was mentioning it as an example because I've gotten to watch several shows in genres I don't usually enjoy merely because of how I liked the characters and the way they're explored and developed.
I guess Hajime ni Ippo is the de facto recommendation for a well thought out character driven sports series. Ping Pong which someone just did a really great write-up on is also fantastic
Welcome to the N.H.K is a show i can't recommend enough. Itll run you through the complete gauntlet of emotions.
Since you liked non non biyori maybe try barakamon, usagi drop or azumanga diaoh.
Thanks for the recommendations, I guess I'll check some of them out later.
I also forgot to mention I had watched Welcome to the NHK and that yeah, that was a damn good show. I liked that it didn't wrap all things up perfectly as it ended, since it makes sense that it'd take a lot more effort for the MC to get over his deep-seated issues. I also enjoyed the general sense of futility that I got whenever he'd actually end up helping others get over their problems but he'd remain a socially inept hikkikomori NEET, only improving very slowly as the show went on but without fixing everything (and actually barely fixing anything) by the end.
Still, the general sense of helplessness and futility of NHK meant I often watched it when I wasn't already feeling down, since it sure was emotionally draining to watch.
Edit:
Btw, I just want to mention that yesterday I tried to watch that Rakugo show, but it was so good I had to stop after 20 seconds. No joke. I was watching it on train, but it opened with such a compelling period setting in terms of production values and direction that I felt it would be a waste to watch it that way.
Seriously. It's one of the outliers in terms on themes and setting due to being fully grounded in reality and focused on rakugo, which I had never heard about prior to watching this. I'm also intrigued by how the rakugo we saw so far always work like some kind of parody of social stereotypes, which is just like a theatrical genre that was very important in Argentina during the early 20th century, only with a single person acting out all the parts and with very limited movement, but still placing an emphasis on gestures, postures and mannerisms. I think I'd call it one of the hidden gems of this season, mostly because it doesn't look like it's going to be too mainstream.
