You'll like Warcraft II more if you play this first.
Seeing as it is the original in the chain of X-Craft like games, it is generally good. Creative theme and original battle system.
It was a bit slow and predictable. The levels got repetitive after a while.
The Bottom Line
If you have never played Warcraft, I highly suggest it. You manage units on a battlefield in order to accomplish a mission given to you at the beginning of each level. You train and upgrade your units at the expense of your available natural resources (Wood, gold and food) and build buildings with different fuctions in the same manner.
