Dolly Parton dying hits so hard. She felt like one of those figures who always was and always will be. She felt like America when it was trying to be the place it promised to be. As beloved as her music is, it’s even better than people give it credit for. There won’t be another one like her.

Here's my latest completed cartoon homage from the 50 Years in the Dungeon show. It's my creative tip of the cap to @larryelmore.bsky.social's cover painting for the original Shadowrun RPG ... a true classic!

Madison, WI has been fun. Expensive though

Personally I'd go with an Addams Family pinball machine! But if you dig it. It would make an amazing addition to a basement bar situation.

So I finally self published a thing. It's for Public Access, but it's hopefully going to hit those nostalgic feelings from Salute Your Shorts and Freddie Krueger. legacy.drivethrurpg.com/product/5647...

Did you know I stream games on Twitch? Still learning the ropes to making excellent content but the games speak for themselves often enough. Hopefully some new ones to schedule soon!

@pushinguproses.bsky.social Hey Roses! I wanted to see if you had any interest in sitting down for a TTRPG session for stream that takes place in a Cabbit Cove analog? Brindle wood Bay calls to you! Hit me up if your interested!

One of my personal favorites. It would have done infinitely better had it released a few months earlier. Nothing could stand next to the Matrix.

This is some of the best art around. Mimicking the old school black and white line art but definitely its own thing as well. I absolutely love it. Wish I could host stuff like this on Nullsheen.com!

The focus on mechanics vs story was a game changer. Even more so when the tools you aee given drive story. GM intrusions finally let the players feel rewarded for opening that door they know will be bad for their characters bur great for the story.

Yup! There was a DnD 3.0 version of Gamma World that was exactly that. It gives the Kingdom a character sheet and feats which changes what the players have access too and the likes. It was pretty slick! Could be modified for fantasy for sure.

Modified art from the Shadowrun 2nd Edition rulebook: a hacker punk sitting in a computer chair with a wire connecting his mind to the Matrix convulses in pain as government scientists look on in horror, his brain likely being cooked by something in the machine…

The image is modified to make a scientist in the background exclaim: “You let him listen to Pink Fohawk?! Turn it off! It’s too fraggin’ rad!”

You absolutely ruled that role my friend. I can imagine it's hard to summon up that kind of evil, but truly. You deserve any award they offer you for it. As the Dude would say, your character was the rug that tied the room together.
