Forum:So what's the deal between GTA Wiki and Grand Theft Wiki?

I'm sure this has been adressed more than once, but couldn't quite find it. I've always been using and contributing to this wikia, but I've also known there's a wiki called Grand Theft Wiki. They have less pages and edits, thus I prefer this wikia of course. But many of their articles are the same word-to-word, some just shorter. Also they seem to have a tad more images on different articles. Is this kinda similar to the 2 different TF2 wikis, or is there more to this?
