I consider System Shock 2 to be the best PC game ever released. Also the music is godly, which really brought it to the top of my list. It has amazing music, a very-original storyline (in video game history), it is the scariest game I have every played (besides Silent Hill XD), and Bioshock was made by the people who made this, so image Bioshock 100x better. That is the sheer amazement I get whenever i play this game. Seriously, if you are bored, download it. It's vaporware and only 200mb. You won't be dissapointed!!!
