Does this run code every tick?

No. The mod has no runtime control script and does not register on_tick.

Does it use resource-depleted events?

No. It changes resource prototypes during loading instead of refilling entities at runtime.

Does this require Space Age?

No. Space Age is optional. Space Age resources are handled when the expansion is active.

Does it work with modded resources?

Yes, when the modded resources startup setting is enabled.

Is this balanced?

It is intentionally a cheat/balance-changing mod. The goal is infinite resources with minimal processing overhead, not vanilla progression balance.

Does this affect achievements?

Do not assume achievement safety. Mods and cheat-like resource behavior can affect how you want to treat a save.
