Simfarm was one of the first sim games that I have played. Your duty is to control your cattle and your plantation. The sheep, goats, cows, etc. need extra attention or they would run astray. It was a good game.
Now, they are making it real. Read this link , which I got from theage.com.au.
I wonder if that could be use for tracking students.. Hmm..*since they are continually skipping classes..
