The classic first game in the warcraft saga that started it all
The story is set in Azeroth in a fight between the Humans and Demonicly corrupt orcs that seemed to come out of nowhere in a struggle for dominance. The campaign missions usually vary between constructing, maintaining and defending your base, and annihilating the enemy base, while the enemy is trying to do the same thing, as well as dungeon missions where you control a bunch of units and must fight your way through some sort of cave and accomplish some sort of objective.
While Warcraft's gameplay is quite dated, and many things like no rally points, you could only select 4 units at once, and even then you had to use SHIFT then drag a box around the 4 units you want, and probably the most annoying of all, the lack of the ability to simply Right-Click on an area with a group of units selected to get them to move, you actually had to press the move button (or press M) and then target the desired location, Warcraft is fun in its own right.
