I know this "feature" too
.
But especially in the map conflict ( I think it is conflict ) this is not a good idea
. I f the opponent CPU sees what happend .......
Maybe this terrain modification is something for GAE too, but I cannot imagine how to create an AI which will use this the right way .....
But I like this "bug"( I personally think its a feature ) the way it is now! In multiplayergames and big maps this sometimes results in interisting attacks
