Pros:
 * We get exclusive free stuff, supposedly.
 * Social networking...?

Cons: If anyone has something to add, just reply. Any mods+ can add it to my message, but please leave a note specifying which user stated it.
 * We are the #2 wiki on wikia.com (second only to elderscrolls). Joining an alliance advertises everyone else on our wiki for free. Over a year ago, Tech wanted us to join some Game wiki thing, affiliates or whatever, but that really only benefits others, because they would get more hits from us, while we would get very few in return.

 * Banners detract from actual information. Wikia's ads detract as well, but we are unable to limit those.
 * Wikia apparently does not care about what wikis join, or who the user is that adds the wiki to an alliance, as evidenced by the mainpage edit.
