The Supervillain DLC let you build a giant laser that can help you in the case of an invasion or a revolution. This will add for you an extra map, costume, accesoire and soundtrack, like all the DLCs.

This DLC is great because you can build a new military building. Yes, you can build a new fort if you want more military buildings, but this building is much beautiful and provides you elite infantry, like the presidential palace. This DLC have also a dictator costume that look awsome and a new island, but the most important part of the DLC is the military building.

I see that Tropico 5 share the curse of all the good series, the curse of predecessor. If you already have a very succesful game in your hands, developers are facing somehow a dilemma: if they try to keep the old mechanics and game design, fans will accuse them of copying the old game. And if they try to implement new mechanics, then fans will complain about how the new game spoiled what it was good. The curse of homm3 over its succesors is the best example of that.

In case you had great fun playing tropico 3 or 4, this game probably won't give more to you only because it's developed few years later. In this perspective, i find most of fan's critics are right. Yet, for those who didn't play a tropico game before and for those who seek an enjoyable simulation, i strongly recommend Tropico 5. Particularly the campaign is well designed, and most of all game is fun.
