That moment where they showed the producer and how emotional he was, was extremely touching.
Keep in mind, it's not just any other crossover with any other random franchise in gaming, it's a crossover with MARIO!!
We often forget this because we're so used to seeing him along with all the other franchises and games we're accustomed to as gamers, but Mario IS video games for the mainstream public. He's Mickey Mouse.
Some of these developers who are in their 30s-40s working on this game most likely grew up with an NES, SNES, or N64 playing games like Mario 1, Mario 3, Mario World, and Mario 64 and it was games like that which inspired them to chase their dreams of becoming video game developers in the first place. (Remember that montage they did just before the conference started.) So to be able to work on a video game involving one of, if not THE, character responsible for their love and passion for gaming and to get THAT kind of praise from the man who created him means everything in the world to these guys.
