Interesting variant of Monopoly

Do more loving playing Monopoly Classic, played and replayed, often too long games ... I turned to this variant on the occasion of a promotion from Amazon.
It's a good idea variant, while finding the basic rules of Monopoly.
Only problem was too quick to win! Never tokens "hotel" was used, meant to be used when you have the same color properties, the same batch.
Each time a player succeeds in completing its tower (condition to end the game).
This game may have been edited hastily without being tested.
