This is a great idea for the application of the wiki concept. Currently, unless you're paying for a subscription to something, you're only going to find text-only versions of guides & walk-throughs. This website would go a long way in changing that, but it's only just started, so if you've got the content for a game, go on ahead & post it!

"With StrategyWiki, content never 'dies', and it can be updated by other writers even if original contributors abandon the guide. This is not true with many other sites, which only allow the original author to edit his or her guide; once the author abandons a guide, there will be no more updates, improvements, or corrections. StrategyWiki also maintains all of its content under the GNU FDL, allowing unlimited use within those terms."
