Reddit mentions of My Brother's Husband, Volume 1 (Pantheon Graphic Library)

I believe the scanlation groups respectfully dropped the scanlation project years ago the moment it got licensed for English so the last few chapters aren't posted anywhere. Can you believe it? The official release is already up on amazon

[My Brother's Husband, Volume 1 by Gengoroh Tagame] (https://www.amazon.com/Brothers-Husband-Pantheon-Graphic-Novels/dp/1101871512). Really cool book (manga) that I'd never heard of til Sunday. Great artwork, sweet story, and a nice insight into contemporary Japanese views of homosexuality.

The fan translator for this didn't finish the series, so if anyone wants to see how it ends (it's lovely, and there are only about ten more chapters), there are official English translations released as two hardback volumes or as Kindle downloads (1, 2)... as well as a live action series...

You've already got a ton of great books on that list (including some pretty dark/intense stuff!) but I'll try to suggest a few things that might fit your criteria.

My Brother's Husband is a really good manga. It's written for younger audiences and acts as a sort of intro to LGBT topics, but it's well-written, earnest, and has an interesting slice-of-life style.

It's about a (straight) single father and his young daughter in rural Japan. His estranged twin brother has recently died and his brother's American husband unexpectedly shows up for a visit. He was never fully comfortable with his brother's sexuality, and the American man doesn't know much about Japan, which leads to some awkwardness and lots of discussions about cultural differences and the virtue of open-mindedness. It's heartfelt and often hilarious. This is the most LGBT-centric thing I've read recently.

Lumberjanes is a very popular American comic. It features an almost exclusively female cast (almost no men in this comic) and has a lot of LGBT representation. The main cast features lesbians, a trans woman, and (eventually) a non-binary AMAB character. The supporting cast is also very diverse.

The comic never really focuses on LGBT issues directly, it just has a ton of LGBT characters. It's a young-adult adventure comic about an all-girls summer camp in a magical forest. The girls show up expecting a normal summer, and end up dealing with dinosaurs and Greek gods and angsty punk rock mermaids.

It's a very silly, self-aware, fun comic with a lovable ensemble cast. Great stuff, and maybe my favorite ongoing comic these days. It's still being published as a monthly comic and the back-issues are available in several trade paperback collections.

On to TV...

Steven Universe is easily the safest bet. It's an all-ages cartoon about a young kid growing up with his three magical moms. He's trying to learn how to save the world, and they're learning what it means to be human. It's a little slow to start but once it grabs you, you're hooked.

The show features a rich and diverse cast, a complex backstory full of intrigue and mystery, an interstellar war, characters who actually grow and develop over time (rare in kid's shows) and a lot of very catchy songs. Despite the cute exterior, the show deals with some very heavy themes in a nuanced and honest way. I'm constantly impressed that it's able to do all of those things while still being, at it's heart, a slice-of-life show about a kid, his family, and his friends.

This show is extremely popular, especially among LGBT people, so a lot of the young folks will probably be fans of the show already.

It's available on Hulu, Amazon, iTunes, and anywhere else Cartoon Network shows are available. Unfortunately CN is infamous for being extremely slow to release their shows on blu-ray/DVD, so streaming (or piracy) is the only way to watch most of the episodes.

For videogames, I'd stick with the classic party games. The Mario Kart titles are always a safe bet, as are Rock Band and the older Guitar Hero games if you don't mind buying lots of plastic instruments. I've been playing a lot of Lovers in a Dangerous Spacetime lately, and it's a fantastic party game for 2-4 people.
