Say I've recently finished my worldbuilding for Codename: Foobar. Would the following types of questions be considered on topic? I would not consider them so but nobody else has asked the question and I think it needs to be codified.
How do I stat Codename: Foobar as campaign setting for my D&D game?
Which engine should I use to turn Codename: Foobar into a video game?
How can I work this Codename: Foobar world detail into my plot?
Basically, should the Worldbuilding.SE be only about the worldbuilding abstract, or should application questions be allowed?
