As you roam from city to city there are
countless different
types of enemies that approach you, if you make contact with an
enemy it will initiate a random battle, however if you press square on an
enemy who hasn't attacked you yet, you'll ambush the
enemy and you'll be able to attack first.
The ongoing tug
of war between players and their opponents for territory keeps the game from getting stale as players zip from area to area demolishing
enemies and using flashy moves, but it does get a bit boring after hacking and slashing against the same
enemy types countless of times.
