Also, don't forget this is an OLD final fantasy with random encounters. You know, the ones where most battles were quick!!! No long load times, so waiting for monsters to load while the screen rotates. Summons didn't take forever. None of those, the battle starts by the time a Skies of Arcadia battle could start and finish.
Random encounters are much more enjoyable when the graphics and speed were quick and to the point. That's where this one falls in. It's actually not bad. Sometimes, like said above, it's more often and other times less.
Of course, FFXII will change all that as that seems to be one of the most significant changes to the battle system, I've seen in a long time.
