The goal of Tropico 3 is quaint compared to those many other simulation/city building games. You're not out for world domination, trying to create a utopian city, or even working toward some vague higher ideal. Rather, your goal is simply to keep the people happy enough that they don't overthrow you while accomplishing basic goals such as population growth or exporting goods. Meanwhile, you'll also slowly pad your private Swiss bank account so that you can retire comfortably should you ever be chased from office. It's all quite believable, just a bit dirty, and surprisingly pleasant.
