Use of the CD-Key in MP game

[The Panther]

I am certain, because my son and I have done this in three MP games. It is no different from a single person selecting two races.

I will also say that we will never do it again because it is a complete pain in the a$$. For one thing, it is near impossible to fight a war between the two players unless they never make their moves during the same sitting on the computer. In one of the games, it got down to the Last three players, so I turned my side over to a permanent sub for this reason.

You also have to be careful about the stales. If not done exactly right, a stale for one side is the result. We both got some stales for unexplainable reasons more than once.
