I cannot understand why so many people seem to think this series is so great.
To me, its always been the poor man's GTA.
Plus they just keep banging out the same crap over and over and people eat it up, but then AT THE SAME TIME, give games series like CoD crap about being rehashes.
Maybe, this one is different. I bought SR3 at a STEAM sale for cheap though and still felt let down.
Wha?
Saints Row 1 - I'll give you that it was trying to get GTA's audience and is the worst Saints Row (although I still love it), but it still had brand new things like the crazy fun Insurance Fraud, more customization of the main character (which, at the time, was not as common as it is in games today), and a great cast of characters (with equally great voice acting).
Saints Row 2 - Even more crazy activities and side quests, tons more customization, more great new characters (Shaundi and Maero, for example), a balance of humor and seriousness (see the Red Asphalt mission for seriousness or Bad Trip for humor). A fully fleshed out city with tons of secrets and easter eggs.
Saints Row the Third - While many people don't think it quite compares to SR2 (myself included), it still evolved the series to a point where I find it impossible to say it is a GTA clone. Way more crazy vehicles (hover bikes), awesome weapon upgrades (exploding bullets, fire bullets, etc.), and extremely over the top (but fun) missions including zombies, high tech military enemies, and big "Brutes."
Saints Row IV - C'mon. The superpowers aren't enough to differentiate from GTA?
Even the smallest evolution in the series, which was from 1 to 2, still produced enough new stuff (while at the same time greatly improving the old) to not be accused of "banging out the same crap over and over."
