Saints Row 4 had already been in it's early stages of development after THQ released SRTT. The Enter The Dominatrix DLC was scrubbed because they chose to instead incorporate it into the next game instead because it would have been a waste of resources (plus by that time it was already looking as of THQ was on life support). In fact, what was going to be the original Enter The Dominatrix DLC is whatever way they make it so going to be DLC for SR4, so for all of you who are STILL saying that SR4 is glorified DLC, you need to get your facts straight. Just because that ADDED the story elements of the DLC into the new game doesn't make the new game DLC. Unless of course you're just plain ignorant to logic and the fact that try as you will you don't know the business practices or development cycle of Volition, so stop fooling yourselves.
SR3 and 4 are in the same city, so of course it's gonna have the same assets...duh. So did Saints Row 1 & 2, so does that make 2 glorified DLC of SR1? I guess that means as was stated in a previous post that ALL sequels are just DLC of the previous game, huh?
Bottom line, the game is fun to play, and that's all that matters. Or at least it's fun to play for those who enjoy the change that Volition made to the franchise. Heck, for those of you die-hards out there who choose NOT to play it because of it's changes, I can say having only gotten through 10% of the game so far that I've caught a couple of subtle references in the game that basically troll you in saying "we know we changed the game...deal with it."
And that's the kind of self-aware brilliance that makes Saints Row freaking awesome.
