@infrabeige.bsky.social got me thinking about what a minimalist dot-grid character sheet for Vaults of #Vaarn would look like. Doing some tests.
Minimalist character sheet. Mostly a dot grid in a red color. There are several boxes with diamond shapes and blue lines containing text in a light blue groovy looking font. The box at the top says Name. The next boxes are much smaller and have a cross through them to allow for a minimum and maximum value drawn over the text inside. These smaller boxes have the following text in order: HP, AV, STR, DEX, CON, INT, PSY, and EGO.

More Into the Odd character sheet tests. I'm planning a one shot at a gaming store and I really want something to communicate the simplicity, while keeping room for notes and maps. #osr #nsr
Simple rpg character sheet. Most the sheet is dotted paper. The top has a box for the name and other info. The left top side has boxes for HP, strength, dexterity, and willpower. The sheet is filled out with number, items, notes, a little character illustration, and a crude map. None of the text is important, it is for illustration only.

Made the most basic Into the Odd character sheet for reasons. Might make a tiny blogpost to share the pdf and talk about why. After I clean it up and improve it.
Extremely basic rpg character sheet. Mostly just a gray dot grid. In the top left are boxes for Name, Strength, Dexterity, and Willpower. In the top right are boxes for HP and Deprived.

I've started a campaign of Jennell Jaquays' Dark Tower using the DCC conversion, I do like some of the additions, but I found the book pretty unwieldy at the table, so I've taken on the task of converting the entire thing into bullet points 😅

I was looking at Exalted Order of the Mystic Moose again and I think this is the best room title I've come up with.
Header says "Bog Body Bear's Body"

Made this graveyard sheet so players can write in their dead characters to memorialize. Just started a DCC campaign so this is very necessary 😂 #rpg #dcc #osr

I just got Megadamage and it's really cool, but I'm questioning some of these color choices. Lavender text on a black background with interspersed white art is really hard to read.
Content of the text is unimportant. Photograph of some magazine text. First paragraph is lavender on a black background which is hard to read. Part of this lavender text has white art behind it which makes it impossible to read. The next paragraph below this is white text on a black background which is easy to read.

I haven't painted in over a year, but got back into it for these Cthulhu: Death May Die minis.
Large painted mini of Tsthathoggua. A squatting sloth and toad combo with a pair of wings. Covered in fur and many eyes.Large painted mini of a Dhole. Purple belly and light blue back. Covered in bulbous yellow eyes. It's mouth is open in a fanged roar.

I recently remembered these procedural #sprites I made 8 years ago. I had been planning a big sci-fi #roguelike where you could see you and your crew's equipment. Body and head shape would change the helmets of the sprites. I'm thinking of maybe trying something like this again for a new idea.
Pixel art showing a grid of 6 by 5 side view characters. Each character is just 3 colors and very abstract. They are equipped with random outfits, helmets, capes, and weapons. The weapons vary between different swords, daggers, and sci-fi guns.

Not a movie, but Doctor Who: The Web Planet has human sized ant like creatures. Gonna watch this thread with great interest since I love ants.

Working on more Arthurian pixel art for some sort of roguelike. I need to come up with an actual game, but for now this is more fun. #roguelike #pixelart #gamedev
An array of 5x5 sprites on a checkerboard grid. Each sprite is 20x20 pixels. The whole thing is framed by simple thorns. Each sprite is a solid color. The top row is religious figures. Second row is fairies. Third row is monsters. Fourth row is a knight and dragons. Fifth row is a wizard, a king, and some other people.

Saint John the Apostle witnesses a Seraphim. Working on some more silly #pixelart for my Arthurian #roguelike
Simple pixel art showing a light blue saintly figure kneeling before a yellow angelic lion faced figure with multiple wings. The figures are very simple and only 20x20 pixels each. They are on a checkerboard grid of grey and black that is 5 wide and 3 tall. Surrounding the figures is a border of green vines.

I'm once again working on sprites for some sort of Arthurian roguelike. Taking a lot of inspiration from marginalia. #roguelike #pixelart #gamedev
An array of 5x5 sprites on a checkerboard grid. Each sprite is 20x20 pixels. The whole thing is framed by simple vines. Each sprite is a solid color. The top row is people, an angel, and a deer. The middle 3 rows are weird monsters inspired by marginalia. The bottom row is knights.

This may be the best sprite I've ever made. Weird little marginalia monster with a big ass. #pixelart
An abstract 20x20 solid color sprite. Looks like a strange medieval marginalia chicken with a giant ass and a cone hat.

Today I've got almost all the ship, crew, and captain generation finished. No ship names in there yet, and there are a bunch of other details. But almost there.
Lots of text on screen. A roguelike screenshot. Describes a ghostly pirate crew with various abilities, a ghostly pirate ship with different stats, and a ghost pirate captain.

Working on multiple screen layers for popups, and a treasure maps popup for my #7drl. The overall world map here is a little odd, but I think it'll work. The idea for treasure maps is that you'll have to sail until you find an island that matches one of your maps and then travel to where the X is.
Ascii roguelike screenshot. Shows a map screen overlaid on the main game view. The map is mostly brown and very abstract. A title says Treasure Maps, and a subtitle says The Known World.

Working on map generation. I'm going to use noisy voronoi cells for islands. Clusters will be combined in various different ways to form an archipelago. Some islands will be large clusters, others thin strips.

Started working on my pirate themed #7drl project. First thing I'm doing is pulling colors from various Treasure Island frames to make a palette.
Shot from the 1950s Treasure Island of Long John Silver and Jim Hawkins. A palette of several colors is overlaid on the frame.

Amongst the first rpg butts I saw was in Expedition to the Barrier Peaks. I believe this is by Jeff Dee.
Black and white illustration. 4 fantasy adventurers are framed walking away from the viewer, while a brain with legs watches them. The woman in the party is wearing by far the least clothes, but everyone's butt is in frame.

Some tiny party people by Dirk Detweiler Leichty for TROIKA! Numinous Edition. I'm starting to run out of butts. I didn't plan this well.
Some abstract naked people partying on a building. The people are red and yellow ink, while the details around them are red, blue, and black. One person is sitting on the other person and you can see the top of their crack. The bottom person has a bottle of something they're pouring off the roof of the building.

Mutant Crawl Classics cat girl butt by Doug Kovacs. The future is pants-optional.
Black and white ink illustration of a humanoid female cat wearing lots of bands, bones, and spikes. She has a shirt with a short skirt like thing, but no pants. She is holding two daggers and wearing headphones around her neck. The background is full of graffiti on the ground, puddles and mess, and some other characters who have been cropped out of frame.

The Murder Princess by Carlo Tartaglia from Break!! All the character design is so fucking good.
Drawing of a severe looking woman wearing very tight gray pants and various pieces of gray armor. She is holding a large purple poleaxe. She has blue hair in two large buns. She is facing away from the viewer and looking over her shoulder with a glare.

Pengling from UVG 2E by Luka Rejec. No distinct cheeks, but I still like it a lot. Shows that adventurers need less pants than you expect.
An adorable short penguin person adventurer carrying a big backpack and no pants. They have a tiny stubby tail. Another penguin person is in the background facing foreground person. In the distance you can see the ocean.

I'm cataloguing my favorite butts in rpgs. I think Sean McCoy's Mothership space butt is pretty high up there.
Black and white painting of a naked person floating in space. It is very rough, butt the cheeks are clearly visible.
