Cosmic Forge
Read full descriptionHide full description
Cosmic Forge is a deep offline idle game about turning a single iron vein into an interstellar mining empire. START SIMPLE Tap rocks. Upgrade your shaft. Automate with a baseline foreman. Watch a transporter shuttle ore from the mine to the refinery, then to the warehouse, where it sells for Coins. Every component — shaft, transporter, refinery, warehouse — has its own milestone multipliers every 10 levels, so progression keeps unlocking speed and capacity spikes. UNLOCK THE COSMOS Beyond Alpha Asteroid there are comet clusters, planets, moons, anomalies, and singularity zones. Each location type has its own production multipliers and warehouse sell rates — anomaly-grade minerals pay poorly per second but richly per sale. HIRE MANAGERS Common managers enable auto-mining; bonus managers stack passive multipliers and trigger powerful active abilities (instant trips, production boosts, free upgrades). Assign them per mine. Some managers survive prestige. RESEARCH TREE 50+ research nodes across multiple branches — economy, production, transport, offline efficiency, stock capacity, coin multipliers, prestige. Queue active research in parallel slots (expand via Galactic Research). Every tier you complete compounds. PRESTIGE FOREVER Perform a Stellar Reset when the cosmos is ready. Earn Stardust based on your total iron-equivalent across every resource. Spend Stardust on permanent upgrades that carry across runs. Eventually unlock Galactic Ascension — a meta-prestige layer with its own research tree and Dark Matter currency. DAILY CHALLENGES Three challenges per day with streak rewards at 7 and 14 days. Missed days reset the streak but the game doesn't punish absence. OFFLINE EARNINGS Step away for up to a week — Cosmic Forge continues mining at a tapered efficiency schedule and rolls a summary up on your return. Research that was in flight completes while you sleep. COMPLETELY OFFLINE No account required. No internet required. No ads. No in-app purchases. No subscriptions. No tracking. No analytics. No SDKs phoning home. GOD MODE (OPTIONAL) Want to test builds, skip a grind, or just play sandbox? God Mode is free for everyone — a one-tap toggle in Settings (behind a "this may corrupt your save" warning, because it really can). First public release — 0.19.0. Thanks for playing through 100+ pre-release builds with us.

Verdict
The clearest difference is ads: Cosmic Forge at none against Eco's shown. Eco's advantage is device support (3 vs 1) and iOS requirement (15.0 vs 17.0). On price, update cadence and in-app purchases there is nothing between them.
