That's what I noticed when I was battling in FFX. I saw the order of person who will get next on side of the screen and I find that very helpful. I was so shocked when I can change the party member on the fly during the battle.
Man, I'm sooooo digging FFX so far. It's something that I had been looking for a while. To truly feel very immersed in story and world, which I don't get from MMOs.
