Similar to my Solium Infernum post, Armageddon Empires works under CrossOver 8.1.4 without work on my part. Yes, there's a Mac version of AE, but it runs rather slow comparatively. I haven't played near as much AE under CrossOver as I have SI, so I cannot speak with complete authority; but AE loads, it processes turns, and it runs smoother than its true Mac counterpart.
Since they use the same technology, I'm running AE and SI under the same bottle. As mentioned in my SI post, I don't like the border, so I force a 1024x768 desktop so that the game always runs windowed. Besides, it's nice to play, browse, and email simultaneously. :)
