I tell you, the GBA games were just great for castlevania, and the same goes for the metroid series! i wish there were more, or at least a motivation to create more of just pure 2D awesomeness. Bring them to the HD realm, but keep them fresh and multiplayer is always welcome! castlevania HD was the first step for these games, although lacking, it was amazing to play castlevania multiplayer. we need more 2D RPG's and exploration games with RPG properties, item collection, armor, weapons, and level advancement. Thanks for your vote!
I was playing all 3, still about halfway through the first GBA one. Like that one the most cuz that is the one I am on now. DS Castlevania games are even better. GBA looks so much better on a computer screen.
