Thanks a lot for all of those who participated to the BuildCraft 2.2.x 2011 worlds contest. There are some very impressive pieces of factory among your submissions!
The decision was though, but the winner is:
The second place is attributed to:
And it pretty complete offshore platform!
The third place is attributed to:
An quite surprising base, with a lot of wirering underground, offering a fully automated refinery, quarry and a small power plant.
The 4th and 5th places are respectively attributed to TheElm and MarijnS95, who make it into the package. Congratulations to everybody, and thanks again to all the participants!
