r/games what is your favorite opening title sequence in a video game?

What is an intro sequence or title sequence that has really impressed you? I love the feeling when your so immersed and enthralled in a new game that its title sequence sucks you in even more. Two that I could think of in recent memory were ME2, and Deus Ex: Human Revolution. Jesus, the intro to Deus Ex is badass.
