User Rating: 9.5 | Saints Row: The Third PC
One word: Fun. Lots and lots of it. It's full of over-the-top action, a witty storyline and crazy and varied missions. Logic and reason have been chucked out of the window to provide a complete gaming experience. The large variety of unique weapons and vehicles are a huge bonus - I loved the Apoca-Fist. (Who needs guns when you can smash through enemies with your bare hands?) Even the side missions are engaging and cannot be ignored. The "gang war" scenario adds a realistic touch to the game, as you are immersed into the role of a Third Street Saint, battling to claim your territory.
The GTA comparisons are unjustified as they may seem similar games, but SR3 is nowhere as serious as GTA but focuses on being wild and absurd, which makes it an even better game in my opinion.
Being a GTA fanatic, I was pleasantly surprised by this game.
I can safely say that SR3 is one of the best games I've ever played.
