If you liked the other Castlevania games on the Ds this would be another solid edition.
Such as the main characters, I really didn't have a good feel for them. Jonathon seemed a bit whiny and never gave up the spotlight for his partner. On top of that, they took out my favorite part from the previous games. Collecting all the souls and in turn using them to defeat other foes. Though they had something kinda of similar it was just not the same. The great parts about the game aside from the standard graphics, sound, gameplay. Was the team system, it added a unique fresh turn to the series where you had a partner running with you at all times. Which added a new game style to the genre where you could switch back and forth using the different play styles. I enjoyed that very much along with the quest system which had you either performing special moves or collecting various items to complete the quests. That alone added some extra gameplay which I loved seeing how Castlevania games are very short to begin with. For the replay value of the game they added the quest's but on top that they added online play along with a system where you could go online and buy all the different type of items and weapons other people have gotten in their adventures and in turn sell your loots. Also with two different endings depending on how you finish the game. Thankfully you can see both with just one save. By completing the game with the good ending you also unlock two different characters *four in total if you count there counter parts* that you can use to run through the game. Check out the FAQ section to see how to unlock a third character as well.
Though the game to me wasn't as solid as Dawn of Sorrow and Aria Sorrow it's still a great Castlevania game and worth the purchase.
