IV- I might be biased here. It is my favorite one.

V- You have to finish this one first before you can judge it. I thought it was rather mediocre except for the job system. Upon completion and reflection, I couldn't have been more wrong.

II- This is another one that you have to play a few times. I had to beat this one twice to realize how great it is.

I- The original is great in a few ways. But a lot of things it's done were bettered in later entries (which should happen by the way)

III- This one was innovative, but terribly unbalanced. The DS version made me like this one even less.
