Lunar Farm
Run the farm that keeps a lava-tube colony alive. Drag out pressurised grow halls, sow them, and balance power, water, oxygen and carbon through a fourteen-day lunar night. The crop roster is drawn from plants that have actually flown.
Play nowArtemis City
Found a colony on the rim of Shackleton crater. Zone habitation, trade and industry and watch density rise on its own along the roads you run, mine the permanently shadowed floor below for water ice, and launch rockets home — continuing straight out of Lunar Farm's closed-loop agriculture as one zone among several.
Play nowLunar Metropolis
Sculpt crater terrain, then build a city on it. Every tile has a height, and sunlight is derived from that height — so the rims are peaks of eternal light worth fighting for and the shadowed floors below are where the ice is. Run transit tubes, power conduits and atmosphere mains, set the tax rate and five departmental budgets, and grow an outpost of bermed cans into a skyline with traffic in the streets. Eight wonders, each locked to ground you had to find or make: a space elevator, a far-side radio telescope, a lunar Eiffel. Then drag open a rotatable globe of the real Moon — near-side maria, far-side highlands, the actual poles — and found a second city somewhere else entirely: flat sun-drenched mare, or rugged crater-choked highland, each with a genuinely different siting puzzle from the one you just solved. Every colony you found stays exactly as you left it, a click away on a Colonies list. Hand the whole thing to the AI director, make everything free in sandbox, and arm the disasters — or the flying saucers — if you want them. Nothing here can end a run.

Lunar Habitat
The vertical-builder formula upended: the surface is the worst floor in the building. Tower upward for sunlight, observatories and comms, or dig downward level by level where the rock itself is the radiation shielding.
Play nowThe Boring Mining Game
An ISRU mining programme run one drone at a time. You pilot DRONE-01 and the rest of the swarm is autonomous — bore through regolith and basalt, haul ilmenite and volatiles back to the plant, and drop scent beacons the swarm will follow.

Original code, familiar shapes
These are new games, written from scratch. They take their shape from the Maxis management sims of the early nineties — a map you build on, a tool palette, a simulation that answers back — but they share no code, art or data with them, and none of those games is distributed here. The originals are still someone's property; this is homage, not a repack.
Where a number could be grounded in real research it has been: the crop list in Lunar Farm is made of plants that have actually been grown in orbit or are long-standing candidates for bioregenerative life support, and the lunar day, the carbon loop and the power budget all behave roughly as they should. Artemis City continues the same ethos at a colony scale — it's sited on the rim of Shackleton crater for the same reason NASA's Artemis program is, and the ice, regolith and helium-3 deposits it surveys follow the real geology of a permanently shadowed polar crater as far as a playable map allows. The exact values are tuned to make a good game, not to publish.
The other lunar games live in the Lunar Arcade, and the CoSE Arcade is the front door to everything — including Settlers of the Moon or Mars, Brute Bowl and the Lunar Red Alert conversion.
