Saints Row is like raw meat - once it's cooked its delicious, but when it's not, it's not eatable.
the car controls. Well ok, this is no sim. Nor GTA is. But in GTA i actually feel like I am driving a car. In SR.. I don't. In SR its like you're skating or something. The cars dont feel heavy at all, they are just pillows to navigate around the streets.
What's even more funny is the gun recoil/physics. In GTA is much more accurate, and fun. I mean, in SR you can shoot someone from 2 miles with a handgun, not realistic, but not even funny - it ruins the game for me.
The story is alright. I don't like gangsta stuff, so I can't be objective here.
The soundtrack hurts my ears, but once again, it's only my subjective opinion.
I say; rent it. If you like it, buy it. But there's a great chance you won't - don't be sad, 1 year from now and GTA is coming for every systems out there.
