This game is just so much fun. I am more of an occasional gamer favouring the Halo / COD type games. Borderlands 2 wipes the floor with them.
It is the fun element to the game which makes it so good. The other aspects of the shooter games are all there - the skill, the gameplay, but it is the imagination which sets this one apart. The sheer anarchy of the game, the great end of task bosses - in many ways it has the feel of the old pre xbox/playstation games with big end of level bosses(showing my age here but I am thinking back to the old Nintendo classics of another era) But this is all done around a good story and great graphics.
It is the most playable and fun game I have played in ages - yet its also difficult enough to take some time. Personally I found Halo 4 to be too quick an experience. With Borderlands, being thrown back to a regeneration point each time you die means replaying sections of the game over and over as you refine you skills.
Excellent. Great fun. A very unique game.
UPDATED - 2 weeks into the game and its addictive. As you advance through, enough changes in the game environment (new adversaries, new weapons, new scenery) that it keeps your interest. Much as I love the Halo series, the game set up becomes repetitive after a while. Borderlands 2 remains fresh. My praise for this game is enough for me to even say that its possibly my favourite game. Ever. But be warned, the tasks will end up consuming many hours of your life!
