There's still some developers left that seem to take pride in always delivering super polished, well-tuned, perfectly tested games. To them, a single bad review of their repertoire seems unacceptable.
For example, there's Polyphony Digital (developers of the Gran Turismo series - they also made a Space Harrier-like shooter at one time, I think), the team that made ICO and its sequel Shadow of the Colossus, and of course, Blizzard.
These are developers I'd probably blindly buy a product off, but well, that's just three, in a world saturated by thousands
