Great game, bought it yesterday after losing some hours plaing it online. It is not so small that it fits in a pocket. like cinq-o. It is portable though.

I also bought risk express, not played that one yet (designed by Reiner Knizia)

When playing it (monopoly express) for real, I found that the calculating your score bit is a bit troublesome sometimes.

The rules in the manual are also a bit different.
When going for the electricity/water or train properties you're not allowed to add the extra die, because those are not the correct properties.

Regards,

Marco
