Business Simulations to demonstrate benefits of ERP? MIT's Beer Game +

Do you know of some good, relatively inexpensive business simulations to demonstrate the benefits of end-to-end Enterprise Resource Planning (ERP)?

I'm looking for something like:

1) MIT's Beer game - http://web.mit.edu/jsterman/www/SDG/beergame.html

2) CAPSIM Simulators - http://www.capsim.com/business-simulations/homepage.cfm?CFID=647931&CFTOKEN=67986400

3) Industry Player - http://www.industryplayer.com/

And in particular, I'm interested in your opinion of the suitability of these tools to demonstrate the benefits of ERP.

I'm teaching a Master's level class and can either run the simulations on the web - or on applications downloaded to PCs in the lab.

Any help you can provide will be appreciated.
