Wikia sites
Any game that has reason to have a wiki, usually has two.
One will be an informative, well-maintained wiki hosted by die-hard fans. It contains every fact about every game in the series, including spinoffs and non-game media. In-depth stats and strategy, obscure glitches, version differences, modding information, lore entries, dialogue transcriptions, pre-release info and previews, beta versions and cut content, no stone goes unturned. This wiki contains anything you will ever want to know.
The other will be a *.wikia.com website. Once it chugs through loading all the Javascript, cookie-laying and video ads, it will have entries for the most popular and/or recent game in the series and nothing else. It won't even comprehensively cover that, leaving entire pages blank and devoid of even a screenshot. What articles are there will be copypasta'd wholesale from the official website or the older, better wiki. There is no consistent format, with technical game information going right in the middle of lore and vice-versa. Expect to see broken HTML and incorrect formatting. Well, expect not to see it, because Wikia is plastered with so much advertising and clickbait that even default adblock lists don't catch them all.
As a final insult, the Wikia-hosted website will be first in any Google results, because Wikia is some sort of weird media empire despite being completely shit and garbage.
