I really loved Borderlands. Shooting bandits in the face to get guns to shoot more bandits was awesome. And still is. Borderlands 2 has better guns, more interesting enemies, better leveling, and better graphics. So why do I end every session going "that is bullshit". After doing that 8 times or so I think that is the end for me.
Ultimately, it was the cars. They sucked in 1 and they suck just as bad in 2. But they are just a patch over the glaring travel issues. There is nothing like running all over to do a mission, only to just be left in the middle of nowhere having to run back. The game just puts so much trudging between my bullets and some jerk's face. I can't do it anymore. If they could have strung the missions in some logical order so you could do a ton at once, or chain them in a big circle leading back to camp. that would be amazing. As it is, the game puts too much between me and its good parts.
I'm sorry Borderlands 2, I love and hate you so much.
