In a couple of actual releases, I can see the Saints Row franchise branch off like GTA did and actually become a competitor to the actual strong GTA line.
Is this a good thing? Yes. Why? I find myself enjoying Saints Row more, mainly for the customization, quirky humor (that seems to be lacking mainly [well, it's in there, but not as much as it was] in the latest GTA games) and other things. Sure it looks "cartoony" in comparison to GTA. But, it has many, many things GTA doesn't offer.
