Looks curious for the result, although they should have added a lot more reasons and options to fill out, even if it took 3-4 pages of what and why.
Still the majority of it looks fairly decent and there's obvious trends. Assuming none of the data is doctored, then it's probably the model that should be viewed overall. (
Ignoring the 60+, $150,000+, trolls)
Cavalary: Sad to see DRM and company issues so low though.
It would be a lot higher if people got burned really really bad. Unfortunately a lot of people tend to be way too forgiving. They'll curse Blizzard for their Servers being down, and then praise how good Diablo 3 is the next week when they can play, forgetting the DRM.
