Double spaces following a sentence is rather immaterial for webpages. All browsers drop repetitive spacing unless it's made explicit with non-breaking space characters. I freely admit that my usage is personal preference, partly based on early typing instruction. I find that it's easier to read, and when typing, it can be strangely satisfying to slam my thumb down on the spacebar twice to mark that a sentence is ended.

Added to acronyms and abbreviations above: Common acronyms where the letters are sounded out, as with DVD player or USB drive, use capital letters. Plurals of these do not then need apostrophes to make it clear that the 'S' is not short for another word, as in the phrase 'burned onto two CDs'. Numbers likewise don't need apostrophised pluralising. Apostrophes can still denote in-term ellipses or contractions however, such as in describing disco as being from the '70s.

Speaking of numbers, those up to twenty, or nice round ones such as a hundred, should be spelled out. That just looks classier. If describing game mechanics and you need the number to stand out, then it's acceptable to use digits. Bonuses and penalties are pretty much always written this way. As an example, a spell that briefly increases quickness may be described as: "This gives a +2 initiative bonus for 3 rounds."

Quotation marks are not needed for emphasis. Italicising for light emphasis or emboldening for stronger emphasis works just fine. I'll admit that I'm bad about this, as I type out the game content in a text file first.

For headlines or section headings, the Level 3 ones (bracketed by triple equal signs) is most similar to the section headers from the original HTML pages. However, on Wikia, if only one level of header is needed, use Level 2. It's easier (by two keystrokes, and there's a button on the editor) and the page layout looks more like Wikipedia. If the chapter or page has subsections (notable examples are the combat and interaction chapters) then Level 2 headlines (double equals) should be used for the primary and Level 3 for the secondary. Level 4 is a thing, but it doesn't really stand out, and is only used very infrequently. If that many differing levels are needed for an organisational tree, bump primary headers up to Level 1.
