I had an o.k game, here :=). I started out good, &, kept on working towards a 5-min attack. When my 1st attack is at 6-min, the A.I finishes up their 1st upgrade, &, that's a BIG bad-point on our side; I'm going to choose to attack at 5-min; so, that I do NOT need to fight enemies that are upgraded..スィー..(;「 ・`д・´).
