Metro Last Light was a previously announced game. AC3:George Washington King was previously announced. The only two games that were announced that were completely brand new, were the "Pain" one (which looks like Ground Zero Metal Gear) and Dark Souls 2. Disappointed with brand new IP reveals, as usual with events like this (including E3).
It's still nice to celebrate games, but wish they wouldn't hype up game reveals when there aren't going to be many. Also, I wish they would stop tagging things as "World Premier" of footage of already announced games. They should call it World Premier "Gameplay".
