Despite it's cool new features, Saint's Row just can't get out of GTA's shadow
Gameplay: Straight up GTA. You steal cars, you recruit homies, you kill people, you do missions, you get respect. Yeah, all that stuff. But like I said before, there are numerous features that lend the game some credit. There's a very deep character creation feature, where at the start, you create what you look like. It's pretty awesome to see your own created Character interacting with the various characters. You can also get a loan, get surgery, do side missions and many other things.
Graphics: They're good, make no mistake, but this still doesn't really look like a "next-gen" caliber title.
Sound: Fantastic. You got plenty of licensed music to listen to and all the characters are voice perfectly. Voice actors like Mila Kunis, Keith David and Michael Clarke Duncan pull off some great preformances.
Replay Value: Just like the GTA titles, even after you beat the story, you still have a lot to do and theres a lot of fun to be had in going back through the story again with a new character.
Ultimately, your enjoyment of Saints Row will depend on how much fun you had with GTA titles and whether or not you want more of that fun on the 360. Despite it's cool new features, Saint's Row just can't get out of GTA's shadow.
