The game is a bit overpriced, you basically have a bunch of NES roms, two Game Boy games, and Super Castlevania 4 (SNES) and Castlevania Bloodlines (Genesis), which are, by far, the best part of this collection.

Games werent upgraded in any way (aside from a quick save feature, which makes some of these games finally beatable), and you dont have much options when it comes to how you want them to be presented.

You have a "book" to see some of the artwork and the original covers for each game, and...that's it.

As of now, I dont know if this is worth $20 bucks, but Konami said a free update is coming which will include the japanese version of Castlevania 3 (pretty much the only version of the game you can play without going crazy), and some new graphical options.

If they do release these features AND you are Castlevania fan, I think this is worth full price.
