A contender of mine would be super smash bros. Melee. Just the symphony is beautiful and the presentation is top-notch.
But it's been topped with Fire Emblem: Awakening's intro. Just everything about it is awe-stunning with no words to describe it when I first saw it (and it was in 3D, making it even better). The music. The CGI graphics. The questioning of the plot. Everything is perfect, and I would be amazed if FE:if could top it.
