From the PlanetPlayStation.com featured review:
"After over 140+ hours of counted gameplay from Borderlands 1, I was ready to jump back into the world of Pandora and kick some butt. Borderlands 1 didn’t end with much of a cliffhanger, even after all the downloadable content, so what was Gearbox to do with Borderlands 2? Throughout Borderlands 2 I noticed there wasn’t much of a change in the gameplay, but it was more of a change in the enemies, guns, and surroundings. Plot wise, Borderlands 2 is a direct sequal with a story that picks up right after the first."
