Just wondering that when playing a normal game of monopoly, can I buy a property when I haven't passed go yet. Anything will help. thanks!
From what I gather from your question the rule you are talking about is a house rule. In the basic rules it is intended for all properties to be sold the first time anyone lands on them. Either from the person that landed on it making the purchase or it being sold in auction.
In general the basic rules tend to make the game faster.
