Our group performed the following TAG analysis on a subset of the command language for Warcraft and Warcraft II. The main purpose of this analysis was to locate potential learnability issues. The TAG analysis showed that on the most part the command language for both is very consistent at the beginning levels. However, it did point out that the Patrol function of the Warcraft II interface should be difficult for the novice user to understand. Because of this we included this as a task in our analysis. Surprisingly, none of the novice users had any trouble with this.

A few differences exist between the TAG for the two versions. First, Warcraft does not allow peasants to attack other units. This inconsistency means that there is a larger difference in the military and civilian actions in Warcraft. Secondly, Warcraft II adds a couple of new commands, Stand Ground and Patrol. Of these, the Patrol function (as mentioned above) had a complicated TAG and was expected to be a learnability issue.
