I bought a Playstation 3 for God Of War 3, and I didn't even have a PS2, I played God of War 3 at a friend's and went "okay, this game needs to be in my house."
Of course I checked out the other Sony exclusives and I've since become a big fan of Uncharted, Resistance, and Infamous but at the time, just God Of War, baby.
And I'm about to do that same thing for Alien: Isolation with a PS4.
Yeah, I know it's on current gen consoles but with Infamous: Second Son already out and Uncharted and Mortal Kombat looming on the horizon, I think it's about time.
