THis is the amazing game that started the genre of "survival horror" and created the interest in fans for such games.  This game is pretty old now, but if you haven't played it yet you'll surely want to give it a try.  The point to this game is simple: survive a mansion full of zombies, while solving puzzles along the way.  What makes this game a challenge is the fact that you have to fend off enimies with a very limited amount of health and life. ANother challenge is that occasionally enimies will pop out and give you a surprise which you must quickly defend against.  ANother great thing is that on this version of the game you get a special edition of Resident Evil and a harder difficulty level.
