First update released for this (unique?) farming simulator. As usual, NFO contain all changelogs for this 2.1 build. That’s all.

 The long awaited sequel to one of the best selling simulations of all time
  brings the intricacies of farming to the desktop, with stunning new
  graphics and a myriad of new features, Farming Simulator 2011 is the pick
  of the crop!

  In career mode, play the role of a young farmer and experience the varied
  daily life on a farm in the completely re-designed, freely accessible
  world.

  All new in Farming Simulator 2011 is the option for livestock breeding. To
  be successful your animals will need proper care and attention, with a
  full feeding regime. In return, extra revenue can be gained from selling
  fresh milk to the dairies and even spreading organic fertiliser over your
  fields!

  If crop farming is more to your taste, build up your farm income by
  growing a wide range of crops including barley, corn, rape and wheat.

  However you structure your farm you are sure to need mechanised help. As
  your income grows take the opportunity to invest in everything from
  tractors, combine harvesters, ploughs, seed drills to balers and loaders,
  all lavishly detailed and fully operable. With licensing from machine
  manufacturers such as DEUTZ-FAHR, KRONE, HORSCH, POETTINGER and VOGEL &
  NOOT, you are able to drive machines that are faithful to the originals in
  every respect.

  No longer is farming a solitary affair thanks to a unique multiplayer mode
  in which you can work on your farm together with your friends via an
  Internet or local area network connection. It is even possible to create
  and download custom vehicles and tools, via an integrated "modding"
  feature.

  Whatever your chosen play style, Farming Simulator 2011 lets you sow the
  seeds of agricultural accomplishment!
