To follow up on a previous post about agile coaching games... today, Infoq posted an article about the session run by these guys at Agile 2008.
I'm happy to announce that a game I recently created and tried successfully in my own company was submitted and accepted by Don McGreal and Michael McCullough into the Tasty Cupcakes wiki.
If you would like to try the Train Game and have questions, feel free to contact me. I'd like to polish it up a bit and improve it based on other people's experiences since I have only run it once.
Update (10/27/2008) - another good post on agile coaching games.
