Here's what it includes, with summaries from Steam:

1)TROPICO RELOADED (Basically Tropico 1 with expansion and Tropico 2)

The ultimate game compilation for hobby-dictators and those dreaming of their own Caribbean island. Tropico combines real-time strategy and simulation elements with a healthy dose of political intrigue and Caribbean flair to create a unique and critically acclaimed game experience.

2)Tropico 3 - Steam Special Edition (http://store.steampowered.com/app/23490/)

Didn't want to paste the bulletpoint summary Steam has :P

3)Tropico 3: Absolute Power

The first official expansion pack to the critically acclaimed Tropico 3 and provides all-new options as ruler of a small Caribbean island nation. It adds a new campaign, new missions, new island types, unique buildings and new powers to maximize the length and success of your term in power.
