Emergent Uptime Tiers
You never pick a tier from a menu. Tiers I–IV emerge every sim-tick from the power and cooling redundancy you actually built. Wire N+1 and the site self-heals; cut corners and it degrades the moment a feed trips.
About the sim
Trillionaire: GPU Tycoon is an isometric, pixel-art datacenter tycoon simulation built in Godot 4. You break ground on a dry desert parcel, build out a GPU datacenter, and grow it from a single cluster into a sprawling compute empire - while fans break, trucks unload, and workers need somewhere to sleep.
The core tension never goes away: the reliability you build - spare power feeds, extra cooling, redundant everything - fights for the same money, power and land as the capacity that earns you contracts.
Win compute contracts, install GPU clusters to serve them, keep power and cooling redundant so a single failure never takes the site down, and hire crew to repair faults before they cascade. Run the numbers right and revenue compounds. Let costs outrun income and the parent company repossesses the site.
Level 1 - the desert - is an open sandbox with one soft goal: grow cumulative earnings to $40M to found The Diggy Hole Co. and unlock The North. Reach it and you win the run. Fall to insolvency and it ends.

You never pick a tier from a menu. Tiers I–IV emerge every sim-tick from the power and cooling redundancy you actually built. Wire N+1 and the site self-heals; cut corners and it degrades the moment a feed trips.
Uptime Tier (reliability you build) and GPU Gen (compute you can afford) move independently. A Tier I hall can run the newest silicon; a Tier IV hall can run the oldest. Neither gates the other.
Levels, GPUs, buildings, contracts and every price live in JSON. The whole simulation is tunable without touching code - and patchable over the air.
You run a parent holding company and found a subsidiary for each region you conquer. The HUD chip always reads EHX · Desert Compute Co.
The Level 1 desert demo is free on Windows and macOS.
