Anno 2070 demo (too short for great game)

Yesterday, the demo for Anno 2070 came out.
The demo features 2 missions of the Global Trust campaign, the nice thing is the follow up save of the map.
Meaning that the next level retains the end result of the previous map,which is handy.
In this case you need to build a base and help build a dam on the main island, at the end the dam fails flooding the main island.
The second mision involves rescuing and relocating the survivors on your island, one of the objectives will be to have at least 25 houses.
Knowing this you can build 25 houses in the first mission and don't have to bother that in second mission.

Ok now comes the too short bit, the 2 missions are fairly simple, even with the secondary quests, you'll be able to finish the demo in less then 30 minutes.
