If you guys have any interest, you should check out something like The International, which is a huge tournament held for the game DOTA 2. I am not a big player of the game, but it's basically a strategy RPG game based on team work. It is so complex that most people I know who like it think you need to play at least 200 hours to have the slightest idea what you are doing. 1,000 + before you are any good at all. These guys get in one location mostly and just play tons and tons of the game together.

Anyways, watching the last one was crazy. There was $20 Mill in the prize pool this last year and the drama was real. They also do a very legit broadcast with commentators and talking heads and it's funny to watch if you don't know the game because you really can't understand 80%+ of what the studio guys and commentators are saying as they are constantly using player lingo, ability names, item names, character names, etc. Pretty funny to take in. I was only so into it when I watched some of it but there is drama and excitement to be had. I think purely as a spectacle it has a draw.
Games that he is investing in are a bit smaller, but I believe they mentioned League of Legends which is actually a bigger game and very similar to DOTA 2.
As someone into games and sports I find it interesting seeing games go this direction.
