These are games, not books, but I'm posting anyway. Out of all the stuff in this bundle, I've played Equilinox and Stardew Valley.

Equilinox has a bit of a learning curve but is kind of soothing once you get the hang of it and your ecosystems start taking care of themselves. My most traumatic mistake involved putting my first chickens in an environment they weren't suited for. They all started to die and I just kept adding more plants, hoping it would save them. It did not. But when everything is in balance,  you can just sit there and watch your pixel animals bounce around, eating stuff and having little pixel babies. Kind of nice.

Stardew Valley is one of my top favorite games ever. I think the bundle price is only a little bit of a deal, but the game is absolutely worth it even at full price. Your character moves from the city to an overgrown little cabin and begins farming, getting to know the townsfolk, etc. It's tough, at first, but better once you level up your skills. I'm currently at 330+ hours of total gameplay time and still love it. It's my comfort game. 

Ooh, this Humble Bundle is a very nice deal if you're a Martha Wells fan and don't already own any of the Raksura books. I've only read The Cloud Roads, but I remember it being excellent.

I can't really comment on the rest of the bundle - lots of anthologies, which I don't normally read.

Ooh. Although I continue to struggle with digital manga (I have sooo many volumes I have yet to read), I may get this bundle.

Titles I've read at least some of and enjoyed:

- Land of the Lustrous: Sci-fi in which gemstone-based people live their lives and try to avoid being broken to pieces and captured by creepy beings that come from the moon. It's a weird series, and the world-building and action is occasionally confusing, but it's also lovely and has managed to grow on me. If you do end up finding the action confusing, the anime is streaming free for Prime members (US, not sure about other regions) and is easier to follow.

- Cells at Work: An anthropomorphized red blood cell tries to go about her business while anthropomorphized viruses and bacteria try to kill her, cause havoc, etc. It seems like the sort of series that could get old after a while, but the first volume, at least, is quality edutainment.

- Battle Angel Alita: It's been ages since I last read any of this series, and I don't know how well it holds up, but it's one of the series that first got me into manga. I recall it having dystopian elements and a cyborg main character. Oh, and yes, I've seen the trailer for the live action movie, and I deeply dislike the decision to give Alita big eyes.

Notes on some of the others:

- Pumpkin Scissors: I've read some of this and don't recall being particularly impressed. There are better "post-war period in a fantasy world" series out there.

- Noragami: I don't think I've read any of the manga, but I've seen and enjoyed the first season of the anime. The main characters are a god without any worshipers and a teen girl who gains the ability to see gods like him.

- That Time I Got Reincarnated as a Slime: I've heard that the novels are surprisingly good. I have no idea if the same holds true for the manga.

- Mushishi: I've seen a little of the anime but haven't read any of the manga. The anime is gorgeous.

Nostalgia tempts me to get the full thing - Battle Angle Alita was one of the first manga series I ever read. However, my manga reading tastes have changed significantly since then, and I'm not actually sure I'd enjoy the series now. That leaves the lower tiers. I remember reading The Ghost in the Shell a while back and disliking the amount of text Masamune wanted readers to wade through. The first volume of Inuyashiki was unpleasant and, judging by reviews, it only gets worse from there. The first volume of The Seven Deadly Sins was generic fantasy and an enormous amount of boob grabbing.

That leaves the first tier, with Ajin: Demi-Human. I've seen a good chunk of the anime, and as long as it follows the manga fairly closely, I'd say Ajin would probably work reasonably well for me.

I've played a couple games in this bundle and consider both of them to be good, if you're into puzzle-solving.

Rusty Lake: Roots - A point-and-click adventure game with lots of weird little puzzles. I think it started life as a phone or tablet game. It's a family saga that takes you from the family's beginnings, through a few generations, and up to what is almost the series' present. It's one of my top favorite entries in the Rusty Lake/Cube Escape series and works perfectly fine as a standalone. If you'd like a taste of the gameplay style, most of the games in the series are available for free - search "Cube Escape" in whatever app store you use. My favorite of the free ones is probably Cube Escape: Birthday (although, be warned, there's some sudden violence, a moment when

). All the games have varying degrees of gross or violent moments, but the characters involved are generally pretty emotionally detached from those moments, if that helps.

Obduction - If you have the same Myst nostalgia that I have, you might already own this. I haven't finished it yet - I've gotten through two of what I think are probably three total connected worlds. It has some of the same issues as the Myst games - times when it's difficult to tell what you should be doing next or whether you're even on the right track - but it also has many of the elements that made the Myst games so good. My favorite thing so far has been the moment when I learned that the world of Obduction is actually much, much larger than it at first appears to be.
