How many GB is Idle Regenerator?

0.15 GB

That is less than the typical Role-playing (RPG) game, which needs about 6 GB.

Leave at least 6 GB free: games need headroom to unpack updates.

The figure is the storage Steam lists as required for this game, not a measured download.

Idle RPG with 99+ powers, deep equipment forging, sidekick roster, dungeons, constellations, prestige resets, and offline progress. No energy timers. No pay-to-win. Just depth.
