MediaWiki - One installation with sub-wikis

I'm hoping to create a large wiki related to a particular video games company and all their games. To make the whole thing more user-friendly I'd like to implement what I can only describe as a 'Sub-wiki' system. Basically, each article has a prefix, for example

General:Main_Page
Game1:Main_Page
Game2:Main_Page

These prefixes work as a kind of category. Each prefix has it's own main page and any other pages I choose to put in there, it's own logo, etc, whilst still having the same database and user system. As for the search bar, when on the page of an article with any prefix you have the option to 'search whole wiki' OR 'search this category'. From there I will install and integrate a forum, so that each category also has it's own sub-forum. But I can set that up myself, all I need help with is the Wiki.

So basically, can anybody point me in the direction of a modification or code that can do something similar? I have seen this kind of thing with forums and don't see why somebody will not have made one for mediawiki.

The only other option is to have multiple wiki installations and integrate their user databases, but I am unsure if it will be possible to integrate multiple wikis AND a forum at the same time without painful nights of coding and/or a high risk of screwing up the database.

Any help appreciated.
