Resident Evil II dropped twenty years ago today. If I recall correctly, I think that this is still the highest selling game in the franchise..
I own the Nintendo 64 and Sega Dreamcast ports, but usually play the Nintendo 64 version for the enhanced Dolby Surround Sound capabilities. I personally found this game far too easy.. The original Resident Evil always had me reaching for the strategy guide to get me past the later puzzles, but I completed this game with no strategy guide at all, so that is my only real gripe with it. Music is extraordinarily ambient and suits the surroundings. The progressively worse malformations of William Birkin added that horror element well. Remake was teased a couple of years ago, but still has yet to get an official release date.
