Symphony of the Night was badass!! It's the only Castlevania game I've played from start to finish though. They really should go back to that 2D sidescrolling formula. But saying that, there's a couple of DS games like that isn't there.
There are about a half-dozen or so 2D Castlevanias between the GBA and DS, and just about every single one of them is as good as Symphony or better.
