I think you might be playing the ported version of IV for ps1, am I right? They just gave it cutscenes cause they had the ability to do it whereas back in the days of pixel town they didn't. They look good no?

They expanded on FF VII because that's really the only one that has a good expandable story line. Check them all out, they're really good. Advent Children Complete just came out a little while ago.

I hope that helps. Cheers.

And welcome to EoFF.
