I'll probably wait until they come out with the inevitable "Castlevania DS Collection" or whatever they end up calling it, and then get both as one of those "finish your collection" Steam bundle things when they're on sale, since those bundles tend to have somewhat bigger discounts than individual games.

As for Dracula X, it especially isn't worth it given that it seems to just be a PC port of the shitty SNES port of the far superior PC Engine version of the same game, Rondo of Blood. Nor is it the PSP remake version, either. (Pretty sure Dracula X was never released on the Game Boy Advance, either, but whatever.)

And yeah, I've played almost all of the games back in the day, including these. The only Castlevania games I can think of that I haven't yet played all the way through in some way or another are the really old ones, like the Haunted Castle arcade game (played it a bit on MAME years ago, but could never really get into it much) and the MSX version or whatever of the original Castlevania, the newer arcade game, and the latter two Lords of Shadow games. Even though I've had all three LoS games on Steam for years, I just haven't gotten around to playing them yet. (Oh, and whatever shitty cellphone games or pachinko games they've shat out over the years. Haven't touched those either, of course.)
