Difference between this and Ultimate Impact?

I was wondering if this game is exactly like Ultimate Impact, as in it plays the same or is just a prequel. Or is it a different game that tells the same story of that game as well. If anyone can tell me if it's worth having both games or just the most recent one on my PSP, that would be great.
