There's a Saints Row 2 trailer that basically, and perhaps literally, shits on GTA4.
You know, we all pretty much agree that GTA is a great franchise, but I'm thinking if the guys that make Saints Row would take their basica game (which is basically a ripoff of GTA) and just tweak a few things, they could actually make a better game.
For example, make a real replay system that works, i.e. allow you to save at any point. And eliminate some of the drawn out and unnecessary BORING car chases and/or long drives to the mssion (Think "Three Leafed Clover" from GTA4) and they could have an absolutely amazing game.
But that's just my $0.02.
