Just thought you all would like to know.  It's offered at a discount to folks who already have earlier editions of the game, too.  I had a few quid in my Steam wallet so I'm downloading now.  Figure the best way to counteract bloat on my chaos team is to start a CE team to play against lower PV league teams until they start catching up.

Play Hobgobs only, especially if you've read the 2nd Ed fluff about the legendary Hobgoblin Team
