Borderlands 2 certainly fell short. I'm not sure if it's just worse than Borderlands 1 in every way or if it's not different enough to stand out. Overall a pretty boring game to me. I still go back to BL1 from time to time, but even that game has some flaws that I hope Destiny works out.
No kidding, in BL1 I got an awesome high accuracy acid shotgun kinda early. Was almost sniping people with it, never found anything as good, but eventually the low level made it useless. Im really hoping we can swap out scopes and barrels, elemental effects etc in Destiny
