Can I create my own version of Monopoly and distribute it ?
You would likely be more concerned with copyright law rather than patent law in this case, especially given that as you have noticed, the patents have expired. 

There is something of a precedent for what you want to do. In 1975, Ralph Anspach made a game called Anti-Monopoly (which, by the way, is a pretty interesting game - we owned it, and at the time, as a kid, I had no idea how significant this was). After a little less than ten years of litigation, Anspach won the right to continue publishing his game. However, Parker Brothers ended up with the trademark, licensing it to Anspach, whose game is still in print.

You will probably need to be aware of how copyright law works where you live and where you plan to distribute the game. (If you're thinking about online distribution, then that may mean laws where your customers live, not just where you live or where the servers are.) If you are planning on making money from this, you should consult with a lawyer to ensure that what you're doing is consistent with applicable laws; advice you get on this site is no substitute for professional advice.
