1) BioShock has great visuals. It's always dark enough to keep you on the edge of your seat, yet you can still see the enemies. 10/10
2) The presentation is amazing. The whole setting of a 1950s dystopia underwater is ingenious. it is very unique and it really immerses you in this world. The sound is unbeatable when it's going with something happening on screen. Not many games do this well. The atmosphere in this game of course is a little scary, but it's not only "jump out of no where" scary, but it makes become paranoid of your surroundings. 10/10
3) The gameplay is kept mostly simple. It might get a little repetitive, but the storyline makes you want to continue playing for hours. The only problem is, you might get a little to creeped out to do that. hehe 9/10
4) Like I said before, the intense storyline will keep you wanting more of it. 9/10
Overall, this is more than a video game. It's an amazing experience filled with suspense, fear, paranoia, satisfaction of being able to destroy a Big Daddy, and satisfaction on just surviving as long as you have. This is one of the best game I have ever played. I give this game a 9.5/10
