Does "copyrighted content from the Propeties" include the older Star Trek Games like Bridgecommander, Amarda, Away Team etc?
Those video games are covered in point two of the "Prohibited Uses Section":
You may not use copyrighted content from the Properties, including but not limited to web content, promotional materials (posters, advertisements) or existing licensed merchandise (novels, trading cards, figurines).
In other words, you may not use anything that is exclusive to those properties. For example; you can use Klingons, because they are specifically covered in the "may use" section, but you could not use a race that appeared exclusively in an item of "licensed merchandise" such as a novel or one of those video games that you mentioned.
