ok i dont get what your saying are you suggesting an almost turn based combat?
because if you want that you can play Fallout or Fallout 2
(which are good games i just got tired of the endless shoot once then wait forever)
or just like after doing a certain amout of actions there is a short delay for you to get to get together what ur gonna do next cause thats why they have th neat pause system that lets you still do actions while paused
and if you do that you might as well have it turn based
also it would cut down on the realistic value of the game because if your fighting someone in real life they dont judst stop and let you think what ur gonna do next(unless they suck at fighting)
