Saints Row 2 V GTA 4
 

Well its proberly unfair to directly compare them but since most people do....

Which of the two games do you perfer?

For me its saints Row 2 on character creation alone since I love getting to decide who and what my character will be plus SR 2 is generally more fun and easier to employ your own imagination on and feels more like a game should rather than coming across as a interactive movie like GTA 4 does.
The mission and activities are a lot more varied than in GTA 4 as well.

Though I would have to admit that GTA 4 is a lot more polished than SR2 and is graphically more impressive in most though not all areas, and its mini games such as pool and bowling are far better than in saints Row 2.
Add to that the fact one can ride the the cabs and trains in GTA 4 is a cool thing that saints Row 2 does not have.
