A pep talk is an emotional story that makes you feel good for a couple days. The effect wears off, because nothing was really learned. I explained in pretty scientific terms two significant problems a company faces as they grow. The purpose is to make you aware of advantages you have that you didn't realize. If you are forming teams and collaborating, this will also help guide your decisions on how many people you need, and what you can expect from others.
I'm not sure the definition of a "modern" AAA game even makes sense anymore. AAA games are targeting five year old hardware, so they've already given up on pushing technology forwards. RAGE on the PC looks about the same as RAGE on the iPad. Exactly what makes them AAA? Advertising and having a popular franchise, and not ever doing anything new? Look how many large studios are striking out on the consoles. If it's not "Call of Duty" or another well-established franchise, it's going to struggle. Meanwhile, Minecraft is selling like crazy, and it's not even finished. Casual and mobile make up a bigger and bigger percentage of gamers, so are they really "casual"? No, the days of the giant game studio are at an end. Indie is the new AAA.
