Yeah Saints Row did pretty much build a GTA clone. But to be honest, when your entering the world of third person, open world gang warfare... your always going to be called a GTA clone.
Like McManicMan said, Saints Row pretty much took everything that GTA did in GTA3, GTA:VC and GTA:SA and expanded on it. It did
a lot of things better, and introduced a lot of new features as well.
It aimed to bring the genre back to a fun, humorous style again. With Saints Row 2, they haven't been scared to knock Rockstar for how serious and realistic they've taken the GTA series.
Unfortunately, because it got labelled as a GTA clone... many of the "hardcore" gamers never even bothered picking it up, or played it for 5 minutes and instantly decided it was crap.
For those people who liked GTA for the attraction of running around blowing things up and driving real fast without the fear of missing your favourite TV show... then Saints Row 2 should be back to what this genre is all about
I think the SR2 trailer said it best itself...
"Would you rather watch TV in a game that your playing.... on your TV?...
Or would you rather push somebody in front of a moving train, grab a bazooka blow up half of the city your in on a drunken rampage, steal a tank and blow up the other half then crash a super car at 150mph into a hooker?"
Honestly, I don't see any reason why GTA and SR can't live side by side... GTA IV's long term appeal this year seemed to die after you completed about 80% of the game unfortunately - and it isn't as easy to jump into a Single Player game and just blow things up any more.... which surely was 90% of the fun?
