In a livestream for Final Fantasy XV, Square Enix's CEO Yosuke Matsuda appeared as a special, level 99 boss in the game, which of course went down a treat with viewers.
Starting at 3:02:43, Matsuda shows up on the big screen that Noctis is standing in front of, before descending and attacking him. We're not sure whether this will be actually in the game (our guess is that it isn't), but still, it's a nice feature to get people excited for Final Fantasy XV.
Which real people would you put into a video game?
