I’m trying to track down a book I read a lot as a kid.

It was a large picture book, maybe 8×10 inches. Probably hardcover. Full-page color illustrations. Not very long, if I remember correctly.

It was choose-your-own-adventure style. You were an astronaut/space explorer who landed (or crash-landed?) on an alien planet.

There were mild role-playing game elements to it. For example, you selected a couple pieces of equipment at the beginning of your adventure, and there was a part where you turned to the back and studied a xenobiology index for exactly 2 minutes and then weren’t allowed to reference it again.

You navigated the dangerous alien planet and tried to avoid toxic atmosphere, poisonous plants, and dangerous creatures.

I would have read it (from my school’s library) sometime between ’91 and ’96. I’m guessing it was published in the 80s, but it technically could have been the early 90s or maybe even the 70s? Just feels like an 80s thing.

Would love to track this down. It had a big impact on my imagination and creative inspiration over the years, I’m sure.

Thanks!
