"Wikia is home to over 400,000 communities for fans, by fans. We are often cited as the best source of accurate, dynamic, and fresh fan-authored information that is fueling virtually all aspects of popular culture: console and mobile games, cable and streaming TV shows, music festivals, big movie franchises, major sporting events, anticipated book releases, fashion trends and DIY, food and drink recipes, and current events on an international scale."

- Wikia

And don't forget that there is actually two formerly independent wikias which - by choice - merged with Wikia for their own innovation. These being LyricWikia and Uncyclopedia. They even started out bigger than Wikia, but still decided it was in their best interest to come together with something that is more of a community than just a wiki farm. The people who founded these independent wikis could have easily gone ahead and challenged Wikia's unique system to become a competitor. But they didn't. Why? Because they saw Wikia as a better chance for innovation. A better chance for the wiki to grow. This in itself proves why Wikia is so much different - and quite possibly better - than other wiki farms.
