Hamlet and Other Shakespeare plays

Hamlet has many similarities and differences to the other Shakespeare plays I have read, The Merchant of Venice and Macbeth.  The ghost of King Hamlet in Hamlet serves as a supernatural element similar to the witches in Macbeth which capture the viewers attention.  Both Hamlet and Macbeth take place among the royal family and nobility.  The concept of murder is also present as Hamlet contemplates killing his uncle just as Macbeth killed King Duncan, however, Hamlet's motives appear to be of revenge while Macbeth's were of greed.  The Merchant of Venice presents more legal and religious concepts such as money-lending and anti-semitism.  It also relies on riddles and problem-solving like the Portia's boxes and the contact with Shylock.
