Comment 4 for bug 627361

You are right, I didn't read the complete OP again. However, I am -1 to show how many maps are available in a campaign for the simple reason as it spoils the story a bit.

I am pro showing all campaigns all the time. I would consider it beneficial to make it visually clear in which order the campaigns are meant to be played, but leave the choice to the user to play the campaigns out of order.
