Hey
I've beaten this game about a million times (13 or 14).
I rate this game a 11 its basically perfect except its a little complecated for the scenario editor so here is some tips.
To creat a game where you can play againts the cpu just turn on your grid and make sure you place everthing the same amount of squars away.
e.g. if your building has a gyser 3 squares away from your start location he must have a gyser 3 squares away etc.
If you start out with so and so money he must start out with the same or the cpu will just sit there and let you kill them because you have an unfair advantage.
Later,
We have more cheats and tips for this game here, Starcraft: Brood War cheats
