New Saints Row 4 dev diary explains what Volition was thinking with this one
I can't say what I think about Saints Row 4 until tomorrow, but I will point out that this new dev diary, which is heavy on talking heads explaining what this game's deal is, does a pretty good job of summing it up. It actually is an accurate description what it is, and so if you're on the fence about that purchase for when it releases next week this will be informative.
HOWEVER, this video does show the controversial Rectifier DLC weapon -- you know, the thing you stick in people's behinds -- in action, so consider that before watching the vid.
