I had two posts about Borderlands ready... but I wasn't feeling them. In all honesty Borderlands is a good game. If you have 3 other friends that want to play pick it up. It will keep the 4 of you happy and entertained for a month or two.
The story is sort of weak but interesting. The voice acting is great but lacks variety. The game is very funny and all and all well done.
I recomend Borderlands but I'm honestly not so in love with it I can spend two days posting about it. It has very few things that one can complain about and given the amount of bad video games being released every week that is something to brag about.
