Idle Bazaar is a minimalist, hands-off trade war simulation where grid-based empires compete for survival through expansion, trade, and conquest.

• No player control needed — sit back and watch the empires fight and trade.
• Dynamic resource economy — nations buy, sell, and black-market their goods based on need.
• Expansion and conquest — empires aggressively seize land when others weaken.
• Live stats — see each empire's money, land, resources, and trading activity.

Empires have a population determined by their land size. This population determines their demand for resources along with a unique multiplier assigned every time the board is reset. This multiplier is displayed next to the empire's stockpiles of each resource. Based on this calculation, they will try to have an ideal amount of a resource in stock. If they have more than they need, they will sell to the market (other empires) for money. If they cannot find another nation with demand, they sell to the 'black market' at a steep discount. 

If a country has no money, its tiles are vulnerable to being stolen. Empires prioritize control over resource tiles. 

Values of resources:

Yellow Buzz: $2

Blue Powder: $3

Blood Vines: $6

Sorrow Stalks: $7

Green Sludge: $1

Orange Fuel: $4

Info Panels:

Info panels showcase the remaining empires and display their land and money. If a country has bought more of a resource in the last five turns, the circle next to it will be red. If they sold more to other empires, it would be green; if they sold mostly to the black market, it would be grey/dark green; if they mostly bought from the market, it would be red.  This panel also shows the empire's demand multiplier for each resource.

Controls:

Press R:

A basic particle life sim in 3D. Each particle follows rules around gravity and conversion. This leads to interesting and emergent behavior.

This is essentially this project:

https://15joldersmat.itch.io/bots-of-boria

... in 3D!

Hoping to add new levels soon.

Commands:

Press R: Reset the level with new rules for the particles to follow based on color and shape.

Press 0-1: Go to a specific level. These have things like the size of the particle space, number of colors/shapes, and distance of interaction predefined. 

Press L: Go to a random level.

Press C: Change the color of particles.

Press B: Change background color.

Honestly just speed. I'm much more proficient in Python and just like working with it.

Thanks for the question!

Yes the file size is bigger than I would like too. This seems to be a limitation with the way I convert from Python code to a .exe (Pyinstaller). So most of my games (the ones written in Python), even relatively simple ones, have around this minimum size. 

Definitely something I can look at though. Maybe I can remove some of the stuff that's getting bundled with it and see if it doesn't break anything.

https://15joldersmat.itch.io/abstractia

What is Abstractia?

Abstractia is a symbolic cellular automaton where symbols evolve on a grid through endlessly unique, randomized rules. Patterns emerge, shift, and dissolve as you watch — or intervene.

 How to Play:

• Press a letter key (A–Z) to select a symbol.
• Click or drag on the grid to place symbols like a brush.
• Spacebar pauses/unpauses the simulation.
• Keys 1–6 adjust simulation speed.
• Key 0 generates a new set of unique rules.
• Key 7 randomizes the grid.
• Key 8 clears the board to a blank state (A).
• Key 9 toggles rule behavior (swallow vs. coexist).
• Key 6 toggles generation mode (equal vs. dominant states).

 Features:

• Infinite symbolic evolution.
• Procedurally generated rule sets — never the same twice.
• 26 unique symbol types with optional color mode.
• Pause, paint, and observe how rules unfold.

https://itch.io/s/150360/gridsim-evolution-10-free-release

A brain controls each creature — a simple neural network of weights inherited from its parents, with slight mutations each generation. Over time, through natural selection, creatures evolve to become better at surviving and duplicating. This leads to emergent behavior, where they appear to "learn" how to thrive across generations.

How do they sense the world?

Each creature uses a cone of vision to detect:

• Food
• Creatures of the same color
• Creatures of a different color
• Whether another creature’s bulb is on
• Distance, energy, and age of nearby creatures
• Their age and energy

What actions can they take?

Based on these inputs, their brain chooses from:

• Turn left
• Turn right
• Move forward
• Move backward
• Toggle bulb (also costs energy)

Evolution in action

If a creature gathers enough energy (with higher thresholds as the population grows), it duplicates — creating a new creature with slightly mutated brain weights. Occasionally, large mutations happen, leading to surprising new behaviors.

Predator and Altruist Behavior

White-nose pokes drain and steal energy, leading to predation. Yellow nose transfers energy, allowing for altruistic behavior to emerge naturally.

If any species’ population drops below three creatures (typically, it depends on the exact sim), a new random creature of that color will spawn.

A simulation I'm working on based on firefighting. 

It's straightforward.

Gameplay:

Civilians move from town to town along roads and from their houses to grocery stores. Firefighters move to and fight fires, often trying to prioritize ones near their fire stations/towns. Fire burns things down and turns them to ash. Ash regrows into forest or open space.

Player commands:

Left-click - start or put out fire

Right-click. place fire station and new firefighters 

Middle mouse - place retardant 

R - reset map

M - reset to metropolis mode

W - Wasteland mode, sets everything to dry brush (set before starting fires)

P - Pause

LEGEND: 

H - House 

G - Grocery

FS - Fire Station 

R - Road (Do not burn)

A - Ash 

F - Forest (burns longer than open space) 

D - Dry brush (sets fire easier) 

O - Open Space 

! - Fire 

RE - Retardent (does not burn as easily)

White circles - Civilians 

Flashing orange circles - Firefighters

New features: Metropolis map mode.

https://15joldersmat.itch.io/a-dandy-election

In Wysaddle: A Dandy Election, you are tasked with securing victory points by winning over states on the Dandy Continent. Each state contains cities with different population values, and the player competes with an NPC opponent to gain a majority of votes in these cities. The goal is to win more states than your opponent by increasing your poll numbers in each city through strategic clicks.

How to Play:

• Objective: Win a majority of the 6 states by gaining the most population points in each state.
• Gameplay:
  • Click on cities to increase your poll numbers. Each city starts with a random allocation of votes between the player, the NPC, and undecided voters.
  • The side with the most votes in a city gains all of its population points, and the side with the most population points in a state wins that state’s victory point.
  • After 30 turns, the election is held, and victory is determined based on the number of states won.

Features:

• Victory System: The game uses a winner-take-all system where winning a plurality of votes in each city grants all its population points.
• NPC Opponent: The NPC has strategic targets and will attempt to counter your moves, creating a competitive election race.
• Sound and Music: Clicking cities plays sounds, and background music sets the tone. You can mute/unmute the music during gameplay.
• Endgame: After 30 turns, the results are displayed, showing detailed breakdowns of votes and population points for each city and state.

Strategize, make the right moves, and secure enough states to become the first President of the Dandy Continent!

GAME TRAILER https://youtu.be/i9d-EvSzW2c

My new simulation is on sale for free. I developed it long ago but never took the time to polish it off until now. 

A brief overview, essentially ripped from the store page: 

In each newly generated world, different countries compete for survival and strive to dominate both land and sea.

In perpetual war mode, countries will expand and then break apart, with some of the new nations following old ways and others adopting new ways. These differences are represented by a nation's ideology, religion, and culture.

Countries that share more of these traits in common are more likely to join a faction together.

Factions share resources, which are generated by factories and represented by dots. Resources are used to conquer and defend territory. Countries within a faction will not attack each other, but faction alignments are always subject to change.

A faction's total number of tiles also generates resources. The amount a tile contributes is determined by its development level, which ranges from 1 to 6—the lower, the better.

In origin mode, the simulation starts as one nation before splintering off after the first rebellion. (Note that this can lead to a more uneventful start.)

In winnable war mode, rebellions will not take place, allowing one nation to eventually conquer the entire map. (There is a known bug where nations will sometimes not attack one another on land for an unknown reason.)

Countries will become

much more naval-focused after conquering all connected land.

**CONTROLS**

- Press **I** to see countries' ideologies.

- Press **R** to see countries' religions.

- Press **D** to see each tile's development.

- Press **SPACE** to see alliances/factions.
