Okay guys this is my first Review, and i write it, after i played the first 3 Episodes straight.
This game is lovley, it has really a heart for details and you should take youself some time, to discover as much as possible.
To keep long speech short. You will fall in love with the characters, this story will keep you up until the next morning and you realize you've already missed the first 2 lectures in Uni [just kidding ;) ] .
The best about it is its special hard and unfair Borderlands humor and the badass soundtrack, in contrast to the really well pointed character development.
I would only recommed you to play the first and second Boderlands first, even if it's also fun to play if you didn't do it.

This is just more a short impression, than a real review, but i hope i could help some of you guys.

Cheers
