It's not listed, but nothing immersed me into a game as much as the Mass Effect series did. The universe and characters that BioWare built was extremely impressive. The story was top notch and by far above anything else I experienced. The story kind of derailed in the last 10 minutes of the ME3, but I enjoy the journey more than the destination. Mass Effect 2 was my favorite game from the series, but for the purpose of the thread, the original Mass Effect was the most influential for me, because it start to an amazing story.
For gaming in general the most influential game has to be COD4... Whether you like it or not, it had so much influence on games, and really expanded the yearly installment thing to something outside of sports games.
