Having been to an MLG event for SC2 and Halo/CoD - not at all. There's thousands of people walking around checking out all the games with multiple mainstages for each game. There's lots of sponsor booths with free stuff (I had free Doritos and Dr. Pepper all weekend) and the crowds are SO hype for the games they're interested in. My friend and I sat down next to a group of halo players who happened to be watching SC2, and even though they weren't there for sc2, they could tell when major shit was going down and we'd all cheer.
The production is similar, but the atmosphere is totally different. This is just fucking dead and pathetic.
