I'm willing to give them the benefit of the doubt that they would've put out a better story if their backs weren't against the wall for release, and that if given the chance to release the same number of patches that D2 got, we'd be playing a greater game. It's still good, addictive fun, and they still have jobs in the industry, so they must be doing something right.
And I haven't read the prequel -- is it available online?
