Back in the mid to late 1980s Nintendo had some amazing video games which can stimulate your imagination. One of the games that comes to mind is the classic game of Castlevania.
Castlevania is based on the story of Count Dracula and takes place in the old Hungarian province of Transyvania. This can be a great game when transfered outdoors and can give your kids the exercise they need. This is also a great game to play with your kids during Halloween, due to the subject matter.
The setting is in the courtyard and inside the castle of Count Dracula. Count Dracula is the Count of Transylvania and has become a vampire and has taken prisoner a damsel and it is your mission to rescue the damsel from him. Count Dracula also likes to suck the blood of damsels who he has captured. Your time is limited and you need to rescue the damsel quickly before the count sucks all her blood out of her.
