Castlevania: Dawn of Sorrow

Up until very recently, I called this the best game on the DS, and it's still up there as one of them.

Castlevania is one of the best action game series ever released. This title really delivers. It brings back Soma Cruise from the GameBoy Advance title Aria of Sorrow. Soma is the reincarnation of Dracula, and has control of the evil beasts. He's called upon again, but this time to stop an evil cult who wants to see Dracula return to power and rule the world (and has found other heirs to his throne).

The game is a 2-D action platformer, but with an equipment and experience system that keeps you wanting to level up. You also (randomly with different percent chances) absorb the souls of the enemies you come across and can use their powers afterwards (or powerup your weapons with them). It really gives it a "Gotta Catch 'Em All™" feel from Pokémon.

One of the things that will have you glued to this game is the map. Not only is it awesome to have the map on the top screen and always open, the game scores you based on how much of the map you've explored. Can you get 100%? There are lots of hidden rooms you know (but there might be a soul somewhere that helps you find those!).

Again, I couldn't put this one down for weeks while I finished it. I still pick it up from time to time just to relive the adventure.

By far, a must have title if you own a DS.
