Awesome, fwiw.
They started off with a Pong/Atari/8-bit extravaganza.
The Legend of Zelda Series
Civilization IV - this was epic, they did the intro music to the game and nailed the choir nailed it perfectly.
Sonic the Hedgehog series
Super Mario Brothers series (this included a solo by a pianist whom name I can't remember)
Final Fantasy series solo by the same pianist
Kingdom Hearts theme
Metal Gear Solid series
Tetris
World of Warcraft
Starcraft 1 and 2 (gameplay video of the new one)
God of War series
They had the guy who won the guitar hero "competition" in the pre-show activities come and play Sweet Emotion w/ the symphony which was pretty fun. They did a similar thing with space invaders.
They "ended" the night with Halo 1 & 3..but then..
Had an "encore" performance of the Castlevania series...
and then performed "One Winged Angel" from Final Fantasy 7, which was...well, yeah, beyond awesome. No reason to bring in a choir if you aren't going to perform that song.
