For some peculiar reason, the upcoming release of Castlevania - Lords of Shadow has got me a wee excited, and I've never played a flippin' Castlevania game. Ever!

So just thought I'd ask anyone out there which of the DS titles I should get. I know there are three (to my knowledge) and they've all been pretty well recieved, so is there a newbie-friendly game that could introduce me without killing any brain cells?
