Yeah Crystal Chronicles is good me and my friends have played that 4 player its very fun and you can look past that bad story. As for 5 and 9 the option to go multi player is there. in 5 you go to config and look at controller it should say single and multi. In 9 go to Battle control and go to custom and you can split the characters up there. I hope that helped. Multi player can make those games a bit more challenging because you have to learn to work together which can be very hard.
