How many GB is AI War 2?

4 GB

That is less than the typical Real Time Strategy (RTS) game, which needs about 6 GB.

Leave at least 10 GB free: games need headroom to unpack updates.

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

AI War II is a grand strategy/RTS hybrid against an overwhelming, inhuman enemy who has conquered the galaxy. The enemy has made only a single error: underestimating you. You must steal as much technology as you can, and take enough territory to fortify your bases and launch your attacks.
