How many GB is Hearts of Iron III?

2 GB

That makes it bigger than 35% of Real Time Strategy (RTS) games we have measured.

The median Real Time Strategy (RTS) game needs 3 GB; the largest tenth start at 20 GB.

Leave at least 8 GB free: games need headroom to unpack updates.

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

Hearts of Iron III: Their Finest Hour puts you back in the commander’s seat during World War II. Win the war with new units, strategies and enhanced game modes. Destroy your enemies from within with an expanded espionage system that includes new missions and covert operations. A new battle plan mode allows you to load historical plans or draw your own; all of which can be shared with allies in real-time during multiplayer. Along with the enhanced gameplay there are two new battle scenarios and a new custom game mode that lets you jump straight into the action.
