agricultural simulatior 2013 on sale for charity

Hey fellow Permies. I would like to start this post off saying I get nothing from this charity link. Agricultural Simulator 2013 on sale for $4.00. I am not sure if anything useful can be learned from this simulation. It may even give bad information (modern farming tech) so be aware of that. I bought it to see if a Permaculture design could succeed in the simulator. It will be on sale for another twenty three days.

It looks like for every step on a farm there is a giant machine ready to roll.
