Neither pitch document is in the expected format, which means that they jumped ahead a bit, and didn’t articulate how the themes are being explored. This is content you’ll need to have for the actual guide.
I think the content for the Scribblenauts guide is fine up through the “Game Basics”, but then it starts addressing each of the possible themes. I think the “Creative Problem Solving” is possibly the strongest from what I’m seeing, but any of the ideas could be drawn out. Just choose one theme for each version of the guide though
The “Who wants to live a million years?” game is missing clear articulation of themes, but the content in many of the questions is a good start. However, I would “tighten” the theme insight and world connection questions to focus on the selected theme.
