Greetings everyone! This is Ken Williams.

🎼 That sound. That mountain. That feeling.

If you played a Sierra game in the '90s, you know exactly what we’re talking about.

The logo alone was a masterpiece—audio and visual.

We found a video that captures every Sierra startup from 1989–1999.

🖤 In Memory of Roberta Vaughn

We are deeply saddened by the passing of Roberta Vaughn—a beloved friend, collaborator, and voice in the adventure game community. To many, she was a superstar—radiating warmth, wit, and passion for the games and players she championed.

Before Colossal Cave returned in its modern form, Roberta was already there—supporting, promoting, and believing in it. Her spirit lives on in every adventure we continue to create and share.

This photo captures a special moment—one filled with warmth and connection. “I love how I’m wearing a heart pendant as we embrace,” Roberta Williams wrote. “It just felt right.”

Our hearts are with everyone who knew and loved Roberta Vaughn.

She truly made adventure games—and the world—a better place.

Please take a moment to support her family and legacy in this tough time by using the GoFundMe and Kickstarter links below ⬇️⬇️⬇️

If you are an old school gamer I would say this is a must see.

35 years ago today, Ron Gilbert finalized the gold masters for Monkey Island.
(They were labeled 1.1 because the game was sent back into testing during the final two weeks, prompting a version update upon its return).

A defining moment that launched a legendary adventure!

What are your thoughts on AI and the future of gaming? 🧐

Join the conversation w/ Ken below 👇

[Ken Williams @caboken]

I'm starting to think about what I might do next as a game. Realistically, the answer is probably "nothing". I'm very happily retired and not sure I'd want to tackle a big project. That said, I'm very curious how AI can change games. I'm early in my research and trying to understand how (from a code perspective) game development in an AI powered world works. Specifically, I'm trying to understand the business model.

Anyway .. for those of you who are thinking similar thoughts, this is my conversation with ChatGPT....

https://t.co/clS2yI72PA

Probably the most interesting part of the chat is the comment that 7% of games on Steam are already using some AI. I seriously doubt that, but it does show that things are changing much more rapidly than I had imagined.

There are lots of cultural, financial, legal, and other issues here. We are in uncharted territory!

[Ken Williams @caboken]

A really nice article about Roberta and her games on https://t.co/9mCY3bt4PT today.

https://t.co/9agbvhEeqJ

Unfortunately, if you aren't a subscriber you can't read it. Darn.

Roberta was also in Le Monde a few days ago.

https://t.co/oRFalKpEBA

Once again - the article is behind a pay wall, and in french.

We are honored by all the recent attention.

When we are boating we miss making games, and when we are making games we miss boating. 24 hours in a day is not nearly enough for all we want to do. Oh well...

[🐲 Colossal Cave 3D @thecolossalcave]

Please allow us 24 hours if you’ve sent a request! 😁

Thank you!

100 Free Copies of Colossal Cave for Android Users! 🤖🎮

All info in Ken’s tweet below ⬇️

[Ken Williams @caboken]

Want a free game? Are you an Android user? 🤖🎮

We launched Colossal Cave on Android last year—and ran into trouble. The game’s a beast (1.2GB!), and older phones just couldn’t handle it. Result? Buggy installs + 1⭐ reviews, even though players liked the actual game.

We’ve now fixed that. A huge update just dropped:
✨ Upgraded graphics
🚫 Removed support for underpowered devices
✅ Only phones that can run it will see it

To celebrate, I’ve got 100 free promo codes. No strings—just email [email protected] and I’ll send one.

All I ask? If you enjoy it, leave us an honest review on the Play Store 🙏

Let’s get this game the rating it deserves.
