I recently purchased this add on from Game in a whim, having not played the main game much since release. I have found it hugely entertaining, and would thoroughly recommend it. The new additions it makes are superb, and really give you a lot more options for varied gameplay. A lot of professional reviews are praising the campaign, but I haven't tried it yet as I find sandbox more fun. There is (in addition to the new campaign maps) a plethora of new islands available, new personas, new industries and new edicts. It's well worth the money, and will keep you entertained for many hours. The lack of DRM makes this game especially appealing, as my laptop doesn't have to waste battery spinning a CD (you can play without one). This runs smoothly -I have an ATI Radeon HD 4570 and it looks great. Definately a must have for Tropico fans.
