This is one of those cases where, how much technology advances a series and it's hard to go back to the past game. Still one of my favorite games of all time, but if I was given a second I'd run to a DS and play Dawn of Sorrow

I am totally looking for a copy of DoS. I didn't know it was so rare.

"Castle Corridor" still makes it worth it. 
Still playing it now and then, only thing I don't like is it's difficulty jump after turning into Dracula.

I'm playing Harmony of Dissonance right now. I love me some Castlevania handheld games, but I feel like this one was designed with confusion in mind because there have been more times in this one than any other one where I just got completely stuck.

I'm still rocking out SoTN on PSP.  I'll head back to my DS once I finish it (again) :)
