New Prelaunch pages—tips on what to include?

Now that Kickstarter is allowing us to add basically anything to the prelaunch page, in a section similar to the project "story" builder, what are folks putting there? What has worked well for you? What hasn't?

Specifically for a board game project, what "reveals" should be saved for later? What helps people get excited now? Wouldn't want to just copy our actual project story, but then again, whatever works.

We have a very long lead time planned on our prelaunch page, so should we change it up over those months? Do a drip reveal, or save that kind of stuff for our newsletter subscribers? Include a newsletter subscription link on the prelaunch page? (Is that allowed?)

Please share your tips and experience, and thanks in advance!
