The test game is still against opponents and their game plans. It will not exist in the real version, that was out there as a way to help us test more games and get more eyes on those games.
With this release it will be a slow release. In reality, not much happens on the 16th that you will notice. We'll start rolling out our structures to do the rollover. Bryant and Yost will be the first worlds to rollover, their new seasons will begin on the 23rd. Each of the remaining worlds will rollover as they start their next new season. Official games do not begin till the 7 day recruiting period is over.
I know that change is worrisome to some people, but I'm working hard to make it as painless as possible. I only ask you to give it a chance for a season, if you still don't like the new changes then I'll understand, I'll be hurt, but I'll understand :)
