Bioshock by Irrational Games So this one you can buy anywhere and for many platforms. The game play (coupled with the creepy 1950's music...those songs still terrify me) TERRIFIED ME!!! To the point where I couldn't play much, but I love the story. An underwater utopia goes terribly wrong. Beware splicers in this survival horror first person shooter. If you can get past this, the story is totally worth it.
