I think it depends on the person's interests whether or not it's worth getting.
If you're after the gameplay, then I don't think you're going to enjoy it very much. On the other hand, the graphics and storyline make up for it, especially the ending.
But yes, I think it would be better to play the original game first before starting this one. I started playing CC when I haven't played FFVII and I was a bit confused about things.
I think you'll also appreciate the storyline more if you know what happens in FFVII. But if you don't mind guessing what's going to happen or if you like the characters enough, then buying it shouldn't be a problem. I had to search FFVII up on the net when CC was getting confusing for me.
