Sadly, I didn't even know about Saints Row until 2, but I did try to play Saints Row: The Third. It seems like The Third went in the wrong direction: Blow the insaneness 50x more out of proportion. While the insanity of some parts was fun, the utter ridiculousness it introduced killed my interest before I could get too far. It was purposefully throwing things that made zero since and joking about how it didn't make sense, but while it was acknowledging itself, it was... I really can't explain it. I just don't like how it constantly puts itself over like that. Of course, SR4 is going to do this even more...
Not my place for this.
