i havent seen enough yet to be sure its very story driven but i dont think so. its mostly what SgtGrimmVegas says, Level up, collect loot, hit points, level up skill tree

but all those things are worked out very nice. theres also allot of humor as in funny talking/looking npc's or enemy's. and extreme violent ways to kill someone lol. today i saw someone getting shot with electric and his whole body was twitching while his head was swinging from left to right stuck on a single string of meat rofl.(and a scag flew away 100 meters after getting shot in the ***

) thats probably why its rated Mature

theres also allot of swearing btw lol which can be funny at times.
most games that try to mix first person shooter with rpg feel more like a rpg with poor shooter elements so far but borderlands seems to got it both right

it plays like a shooter AND got great rpg elements/skills in it.
Lilith can turn invisable for a while and blast enemy's upon becoming visable, Brick can go berserk and punch everything to pieces

, Mordecai can send out a bird that will track enemy's and attack them and Roland can deploy a turret on the ground. but those are only their main skills. i wont spoil more
edit: 1 more thing i gotto add which is pretty cool imo, each enemy has their own weaknesses for an element, but also a weak spot on their body where they are less armored for example.. so it really takes aiming skill and knowledge about your enemy to know how to aproach them

cant wait till it releases >.<
