Prettiest among the classic Castlevania games on the NES, and perhaps also the hardest.
In the year 1476 Dracula has ravaged Europe with his army of monsters. Church calls for the current wielder of the Vampire Killer whip, Trevor Belmont. In his fight Trevor has 3 playable characters with him and the ending depends on who he has with him at the time. NES hardware didn't allow much in complex storytelling, so don't play this game expecting something different from that rule.
Graphics are great for the time and this is undoubtedly the most detailed Castlevania on the NES. Music is pretty much recycled from previous games and at times it can get a little annoying.
Gameplay is the one aspect that has seen quite amount of changes. Trevor can choose to use 3 other playable characters: Sypha Belnades, Grant DaNasty and Dracula's son Alucard. Trevor can have only one of them with him at a time and their special abilities are used to make progress in the game.
As it has already been stated: don't expect an easy game when playing Castlevania 3: Dracula's Curse. It's a nice addition to Wii's Virtual Console library and a great way to remember one of the better games in Castlevania series.
