Ink or Sink proved beyond a shadow of a doubt that with the proper commentary and spectator setups, competitve Splatoon is a juggernaut waiting to be unleashed. The game is so dynamic and full of high skill/high entertainment factor moments that the moment it becomes a thing, it'll probably be my second most watched thing on Twitch/in competitive gaming outside of fighting game events.
Seriously, anyone mildly interested in the game or it's competitive potential, just give this a watch sometime. It's a fantastic set between two squads (EDPP and Squid Squad Clubs) that was streamed recently.
Seriously. That's intense stuff. I hope various modes take off. I'd love to see pro rainmaker matches.
