I want to encourage you all to suggest playing Capitalism 2 in class.
I did and it was super great :D
Even our economy teacher was surprised
A few people didn't look in to the game at first and got a bad start, but with a little help (from the bank :) ) they manged their own company quite good.
All in all it worked out very well and it was a nice opportunity to make use of our econmy knowledge.

I haven't tried it but maybe someone is interested to this educational project involving Enlight Software:
