The end of turn button (lower right hand corner, over the minimap) used to be a green/red circle in normal civ. In FFH, it has been replaced with gear-like circle holding the Armageddon counter. Sometimes this number is orange, sometimes it is green. I don't know if this is supposed to mirror the old green/red mechanic, but it does not seem to work reliably. Often the text "Press ENTER to end turn" will display even while the number is still green. At any rate, changing the text of a small number is too diminuitive a visual cue for the important "is it my turn or not" information. Many times while playing today, one of us overlooked the "Press ENTER..." text and made the other one wait needlessly. I suggest changing this back (at least as a downloadable option?) and finding another place for the AC.
EDIT TO ADD: I can see the faint glowing around the button now. Faint being the keyword. How about having fireworks go off continuously while your round is over and you haven't pressed the button yet? ;P
