i'm a monoply buff and have been for years. we have four versions of the board game in the house and play it almost weekly. we love the streets version, while we could do without the orginal one. but hte mingames on the orginal are fun and interseting. we will be adding this to the collection. if you like monoply watch the characters and how they interact with their environment. it's a hoot.
As far as I can tell, I think they added one extra 3d board to the streets edition but otherwise nothing was changed. Except for the way you unlock boards and tokens in the original, the boards themselves were already included in the original monopoly streets so I don't know why they felt it was necessary to package them together. If you don't already have them, though, it's probably cheaper to get the collection.
