There is something that Wikia does pretty damned well and that’s Gaming wikis. If you were creating a wiki dedicated to gaming, they would be one of the hosts I would recommend. Why? Because Wikia has awesome connections in the Gaming community. They’ve developed relationships with game developers and other companies. This has a positive effect on those wikis in terms of helping generate content, getting contributors, etc. They get the companies and people involved with them to help out on some of their wikis. How cool is that?
A really good example of this? Jesse Heinig, one of the developers for Fallout has made a few edits on the Fallout wiki. And he’s chatting with contributors on #wikia-fallout on freenode on IRC. How damned cool is that?
