I posted this in the EVO announcement thread, but I'll post it again.
Even if you're a Nintendo fan and care nothing about eSports/competitive gaming, you really should watch "The Smash Brothers" documentary. If you're a fan of documentaries in general, you should also watch it.
It's broken up into multiple parts. Here's a link (just start on part 1):
https://www.youtube.com/watch?v=6tgWH-qXpv8&list=PLoUHkRwnRH-KTCH3tJ9WvsWWPEgUu-y6dIt's broken into 9 parts and each part is 20-35 minutes long. So the entire thing is 4+ hours.
I've watched a ton of Starcraft 2, but I never followed SSBM. After watching this documentary, I feel like I have a pretty good grasp of the scene (in general) and can appreciate EVO and MLG a lot more when SSBM comes back. (Starcraft 2 is also coming back to the next MLG, btw.)
Anyway, I highly recommend watching it. I know it's a lot, so just watch it one part at a time. You won't regret it.
