I wasn't clear in my first post, so let me reiterate the "Choose Nations" portion of the streamlined SP interface:

When you start a singleplayer game, you choose a nation and design a god, then get sent to the "Choose Nations" screen. But it is now called the "Choose AI Opponents" screen, instead. Your nation is already greyed out and set to human. The other nations can be set to computer AIs, but cannot be set to human. See? Idiot proof! You will always have exactly 1 human nation in the game, and it will always be the one for which you designed a god... which is what people want when playing an SP game, and what sometimes screws up newbies.
