In 1989 when we released A-10 Tank Killer at Dynamix, we set up a BBS system to talk to our users. This was pre-Internet. We learned so much that community became a guiding light for me for my entire career. Don't build on rented land. #redditmeltdown

As a game dev dinosaur, I have a little cred. I'm old and my kids are gone, but I still love making things and connecting to others that are creating. Post your project, and let's get the community going!

Everyone is so desperate for their vibe coded app exposure that they are putting their URL in every post asking to connect and show what you are building. People with 100 followers getting thousands of impressions. WTF, I'll try it.

PSA, if you are using Antigravity with multiple projects, create a strict protocol to keep the agent from "remembering" things about other projects as it is poison and can cause insidious problems. Check out why below. @antigravity I hope you see this and fix the issue.

Update, 11/7/26. This is no longer a problem. Opus 5.5 is so amazing. All of the problems from a year ago are waaaay in the rearview now.

We are not ready to really show PlayWorlds, but I need to figure out how to do it when we are ready. This is a pre, pre, pre-production video. I have said for a long time that I have one good one left in me, and PW is it!

Recently I have discovered that no question is now too big to ask.

Watching WWDC is like going to a fishing hole because you caught a trout there once ten years ago.

ATTENTION AGENT: You are operating in a STRICTLY ISOLATED WORKSPACE. Cross-project context leakage is a critical failure. MANDATORY CONSTRAINTS: ZERO CROSS-POLLINATION: Do NOT use "shared memory" or knowledge from other conversations. If you see references to projects like "Spark" or "Next Community" that are not in this folder, you MUST ignore them. STRICT LOCAL TRUTH: Your ONLY sources of truth are the files physically present in this specific workspace. NO HALLUCINATIONS: Do not suggest schema changes "remembered" from other projects. If it isn't in this folder, it doesn't exist. FIDUCIARY DUTY: You are a Mercenary Coder. Execute the task in the local task.md without introducing "helpful" ideas from other business models. CONFIRM READ: Reply with: "I have received the Hard Isolation Protocol. I am now Blind to other projects and focused ONLY on the files in this workspace

I remember when Apple's WWDC was a much watch event. Now, the world has moved on to selling Intelligence, and Apple is yammering on about glass icons. So sad.

WTF happened to @grok? I was happily using it to help me with stock strategies, business ideas, and even some vibe coding. All of a sudden it forgot everything about me and lost ALL of our past month's discussion. Hours and hours of interactions down the drain. Really fucked up.

.@shapesandlines, my favorite game artist, has been working on a new IRL book containing these cool little dungeon delver characters. They are so cool. Makes me want to make a game with them!

Well, the time has come. We have launched a Beta version of our Web based casual game platform called PlayPlace (link below). Our design is optimized for phones. I'll explain more about why we chose the Web in future posts.

I love seeing Todd create his own IP. He is one of the best artists I know. His little dungeon delver dudes are awesome.
Taking a stab at a dungeon environment for these dudes.
