What goes in a work's description? And how big of edits can we do?

This is kind of a dumb question, but I can't find a good writeup on what should go on a works page description.

I'm currently trying to improve the Old World of Darkness page, and a lot of the information in the second half of the description really feels more like it belongs in a wikipedia article, or at least a creator page for White Wolf, rather than on a works page for a specific game. Am I wrong?

I created a discussion about this, but given the frequency of edits to the page, I'm not sure anybody's gonna see it any time soon. I know we're supposed to ask before editing a trope's description, but what about a work? Can I just go in and fix this, or do I need to create some kind of thread or something?

Just fixing it is fine. Nice pick-up, in fact, noticing that a big chunk of that should be in a Creator article.
