Been playing Borderlands 2. I like it considerably more than the first one. Still not perfect, though. My main problem is the way the guns handle. Firing from the hip is absurdly inaccurate, but the game is simply not built for ironsights aiming. Similarly, the Halo-style health system seems to encourage caution and cover, but the way the enemies behave and the amount of life they have pretty much demands otherwise. I'm sure I'll get used to it in a few hours.
The only other quibble I have is that I'm level 7 and yet I'm a level 55 badass. I mean, that's pretty damn badass. It kinda feels like the game is trying to jerk me off while I play it.
