What IP (book/comic/TV/movie) that hasn't had a AAA RPG should get one?

Middle-earth. It's bizarre that there hasn't been a proper RPG in that setting already—well, not since 1992, at least. I wouldn't even necessarily want it to be AAA, though I imagine that's the most likely option. Maybe if the upcoming TV show and film do okay we will get something.

For me I think it sounds like my wishes are about to be granted anyway, but for the sake of the conversation I always wanted a super hero RPG either with Marvel or DC characters where you play as a superhero and upgrade your skills/powers/abilities as you progress in the story. I've always thought playing as the likes of Spiderman, Hulk, Ironman or whatever would be cool .Which was why i was pretty hyped fo rth eAvengers game at first as I thought it ws going to be something like that.and whilst I loved that game's story and characters I did feel the gameplay was a bit grindy. That and the fac the game was always online we re the 2 main reasons why I stopped playing as the game was starting t ofeel a bit unbalanced towards the end. I hasve heard they changed it recently a bit but haven't got round to play again so can' tcomment on that. Ihave been tempted to go back and give it another shot just haven' thad the time as I'd like to replay the Reassemble campaign anyway

As I said though this is one of the main reasons why I'm personally looking forward to and am hyped for October because we have Marvel's Midnight Sun coming on the 7th and Gotham Knights on the 25th which are both based off Suprehero universes and in these universes ew'l be able t opla ywit hour favouriet heroes and upgrade their skills and abilities.
Sam ewith Hogwarts and Harry Potter end of the year though no official date on that games head yet. Thre is a choice/story driven game coming for th eStar Tre kfranchise in Star Trek Resurgence but like Hogwarts it doesn' t have a release date yet either.

Been thinking about this a bit more. Other than Middle-earth, I struggle to think of settings from books, film, or TV that I particularly want to see in RPG format. Most of the stuff I like doesn't lend itself all that well to that kind of adaptation. I loved the Arcane TV show last year, enough that I wish Runeterra had a game in a genre I actually like.

But I think the best source of inspiration here would be tabletop RPGs. I can think of many of which I'd like to see a video game version:

• Vaesen: folk horror in Victorian Scandinavia
• Runequest: fantasy Bronze Age with a mythological scope
• Pendragon: Arthurian legend true to the sources
• Legend of the Five Rings: fantasy samurai-era Japan
• Spire: doomed freedom fighters in a bizarre metropolis
• Wanderhome: pastoral slice-of-life fantasy with cute animals

Even for a Middle-earth game, the ideal for me would probably be something like The One Ring RPG, based on the books and striving to stay true to their tone and themes—so not terribly action-driven.

Had to Google this, but man…the short story synopses I read were pretty bleak.

I’d definitely be down for some of this.

Expanse, though the requirement to give it an AAA treatment is a bit like a death sentence. That reeks of "all gfx and bling" - mediocre gameplay.

Yes! I second this and let's add Stargate SG-1 and Stargate Atlantis rpg's.

That’s fine as a basic concept, but those books are fricken huge.  Getting half way is like reading the entirety of the Lord of the Rings.

I’ll get around to it one of these days, I’m sure.

Not always, but often.

Won’t be an RPG, though, right?  Another visual novel/choose your own adventure movie game?

Those are fine, but they’re an entirely different beast to an RPG like Mass Effect or the Witcher or even Tomb Raider/Batman Arkham etc.  Harder to get the essence or soul of a setting when you have to balance the gameplay with the lore.

Percy Jackson and the Olympians. Could be also based on follow-up books/series, where premise was expanded to other mythologies. I've always found the idea of gods adapting to current times fun concept, and playing as demigod could easily bring in interesting gameplay solutions depending on who your divine parent is.
If you ever saw the movies but never read the books please do not judge the IP by them. It's one of the titles that got short end of the stick when it comes to adaptiations 

I support this too, and as a gameplay mechanic when we die as either Sam or Dean we're brought back to life.
