Back to HOI2 with the Kaiserreich mod. I'm going to finish this game as the German Empire, go back to HOI2 regular and finish a game as Britain, and then install Kaiserreich again, which will hopefully be out of beta stage by that time.

By the way, it's a great game, even in beta. I'd certainly recommend it. A lot of work went into that mod, and they're still pouring it in.
