Game play gets an 8 out of 10. It would be a 10 had it not been for all the crashing, first round triple A standard bugs, no big deal, they'll fix it.
I like the improvements in driving dynamic, and didn't dislike the driving missions as much as I did in #2.
New guns are great, as well as the characters. Flak being my favorite, followed closely by Moze.
It's strange, but to me where the game lacks is story. I didn't care about any of it. Hammerlock/Jacobs being the exception. The rest wasn't at all interesting. The humor also was contrived. It seems as if 2 was really well written, and 3 just kind of "tried" to force the humor.
The bad guys are still funny, as well as Claptrap, but by in large I just thought the calipso twins were just annoying.
