The people who make your games are real people who often labor under difficult circumstances to do what they do. Thank a game developer or publisher today for the joy they've given you. Thanks for doing what you do, Alan!

Finished board state of a game of City Skylines, with playing cards arranged to look like skyscrapers in city skylines. Each player that sits around the table has an example of a skyline constructed in this manner.

incredible depth, great work
Damn flexible system that allows you to make some of the most off the wall noir detectives you've every thought of. If I weren't swamped with other projects I'd be seeking out a group to play it with right now.
hmmmm..... good game. mama like. nom nom nom.
I really enjoyed reading through it! Can't wait to get it to the table.
A bunch of reviews for Eureka: Investigative Urban Fantasy. It helps us immensely if you leave a 5-star review for Eureka by going to the top-right of the store page, and it would really help us out! Just note that this is one of the rating systems where anything below a 5-star counts as negative.

Cover art for the City Skylines rulebook. Features cracked and shattered stained glass shards that each reflect different aspects of a modern city. Average playtime is specified to be 30 minutes for games of 2-5 players.
Got my first in person impromptu pre-order for City Skylines! Was a little surreal to tell you the truth, but sometimes these things just happen. Here's hoping that such fortune continues into the future :)

Top text reading: "The European Citizens' Initiative is OPEN!"
A speedometer showing progress on the Stop Killing Games Initiative, with the dial showing 1.401503 million signatures, a filled blue bar for the 1 million signature threshold, and 4 filled smaller yellow bars representing 1.1, 1.2, 1.3, and 1.4 million signatures passed.
A button below reads "Sign the EU Petition"
1 million to 1.4 million in 17 days! Incredible! Push for 1.5-1.6 million to have politicians pay more attention to us and build our buffer!: eci.ec.europa.eu/045/public
Come on gamers, gamer allies and relatives of gamers! Let's fight against "own nothing and be happy" and #StopKillingGames !

The City Skylines Playtest went well! Got some great feedback and have added in some more graphical elements to break up the rules text and to clarify a couple of common misinterpretations.

A promo image of the CAPERS ttrpg featuring mockups of the core rule book both opened and closed as well as a character sheet and a custom deck of cards.
A mockup of multiple open copies of the Omega Horizon core rule book open to 3 different spreads. The first features a reptilian alien race know as the Dachians. The left page contains a full page illustration of one of these characters with an overlay containing some basic information. The facing pafe contains more details about this race. The second book is open to the Chapter 7 intro spread. It features a full-spread, colorful, and chaotic illustration of some kind of sci-fi motorcycle race with a vehicle crashing and exploding in the background. There is a small overlay on the bottom of the right page that contains the beginning paragraph of the intro fiction for this chapter. The final book is open to one of the planet spreads. It features a full page illustration of space with a green and ochre colored planet centered on the left page. There is an overlay with more details about this planet but it is obscured by the first book which sits on top of this one. The right page contains further info about the planet.
Mockup of of the cover and an interior spread of of Shadow Over SoL 2nd edition Quickstart Guide.
The cover features illustration of an astronaut waving from inside a dark corridor to other's approaching from a ship across a barren landscape with no atmosphere.
The interior features a spread from the section entitled "Memories" containing information about the setting and a dark, gritty illustration of a closed bulkhead door. The pages are bordered with a texture that looks like sci-fi paneling with wires and displays showing the page numbers and the section title
The book mockups sit on a blood splattered metal surface with a bloody wrench and astronauts arm for horror ambience.
A spread from Entromancy: Definitive Edition featuring a photo-collage illustration on the left page of a robotic hand, and dimensional geometric shapes super imposed over an image of a shadowy figure with glowing eyes. The right page features a double column informational text layout describing the class known as "The Bionic"

Hey folks! City Skylines is ready and raring to go, but I'm going to be running some final public play throughs for the rulebook itself. The idea is to use these as both a way of getting reviews and making sure that the rulebook is written as clearly as possible.

Brickwork themed playing cards splayed to reveal the ten of hearts, four of hearts and the ace of hearts. The Jemstone Games logo of a coiled dragon wraps around the heart symbol on the ace card.
three splayed playing cards show the clubs suit, wood themed and green tinged. The eight, the two and the ace are shown. The Jemstone Games logo of a coiled dragon wraps around the clubs symbol on the ace card.
Here's some of the custom card art for City Skylines. Let me know what you think.

A birds eye view of a city street. On the roof tops of two buildings a street artist spraypaints a purple dragon logo on the side of a UFO saucer shaped spaceship. Meanwhile on the second building rooftop, two men in builders work attire look over a blueprint for a new story extension of the building they are standing on. Building materials and minimal scaffolding can be seen behind the two men.
The image is divided in two by a side on view of a pavement that cuts through the centre of the image. On top of the pavement walks a red headed woman in a blue coat. She walks between shops that flank her on either side of a narrow alleyway. Below the pavement is a basement room with a couch and three guys playing a card game on a wooden table.
Here's some of the artwork for the rulebook of City Skylines, a playing-card based city building game I've designed.
If the art has sparked your interest and you want to check it out and help make it a reality you can do so here:
