Well, I've written a lot of guides, and I update them occasionally. The ones on GameFAQS are always up-to-date, but the ones on other websites might not be.
So I set up this page, which contains all the guides I've written, along with the date of the most recent update for that guide! If it turns out you find an outdated copy of one of my guides on a website, let the webmaster know about it!
And if you're interested in video game guides, I've actually written a monthly column about video game guides. Check that out for video game fun, and information about writing guides.
