I just picked it up last night, and so far it's pretty cool. This is my first ever Castlevania game. Well I had one of the GBA games but I lost it after about of week after getting it and never really bothered to look for it.
Anyway so far it's pretty sweet, I like it. So is the other DS Castlevania any good? I saw it at Gamecrazy for 25$ and if it's like this one I'll probably pick it up.
If you like PoR, then you'll like Dawn of Sorrow. Of course, my view is pretty bias since I'm a 2D Castlevania fan. One minor thing I'd point out is that Dawn of Sorrow follows directly after the GBA game Aria of Sorrow and both star Soma Cruz. You don't need to play Aria of Sorrow to understand Dawn of Sorrow at all, but they are connected. You even get a nice bonus if the AoS GBA cartridge is in the DS when you start DoS.
For a shorter version, yes. :)
