The game is easier than DMC 4, but it's still good.
Taken from review:
Well DMC 4 is a lot more approachable to newcomers than DMC 3 was. Veterans might shun (well should) the easier setting and do their best to work their way to something more challenging. Even though it's easier it didn't turn out to be a sore spot in the franchise like DMC 2 was. Aside from the back tracking that you have to deal with as Dante the game is a blast from beginning to end. For DMC 5 (you know it's coming Capcom will sequel a franchise to death (or re-release it like Street Fighter)) they better include Vergil and give him an actual storyline.
