If Larian had contacted certain Youtube personalities earlier in the campaign, they might have doubled the 1M. I think they learnt a lot for future campaigns (also will depend a lot on how well both DC and D:OS do when they are released).
Yeah, impressed by the idea although it's somewhat an egg of Columbus. The cooperation of systematized media is, of course, appreciated but, for example, I was skeptic about that Gamespot would kindly publish an article about this campaign in a timely manner (It won't hurt to try, though). I think the cooperation of social media gurus is what turned out effective in this campaign. Of course, if they don't have anything to show, it wouldn't have been this successful. So, hat off to Larian's daily diligence.
