This is a suggestion that I think might be rather easy to implement and might even be worth the hassle.
In the options screen there is a single slider for unit activation and delay with four options.
It seems like maybe two option sliders would be better than the one we have now.
One slider for the AI and one for the player (which would be the MP setting, as well).
That seems like a more logical and flexible format which would give players four times the gaming options available now (16 v 4).
Thanks!
