My only accomplisment was beating it. I really didn't like it at all. The main thing I play Silent Hill for is the story, and SH3 offered very little new material. The whole thing felt like it's mission was to dumb down and explain the first game for those that didn't get it. All fresh material was only to conclude their attempt at explaining SH1.

On the otherhand, the game still:

~ Was the most terrifyingly intense of the series for me
~ Has an amazing soundtrack
