Very Impressive.
If you like to see a breakdown of its kickstarter stats check out Kicktraq here. Its trending to between $800k and $1.4million
At first glance gaining $170k on its first day looks a bit suspicious, particularly when you factor in its avg pledge vs backers ($38,000 vs 200).
However digging a little deeper reveals over 1300 backers in the first day and judging by the 600 backers in the $300 reward ($195k) I'd say its pretty clear that these guys have a very strong and loyal core following that are actively watching the company negating the need for heavy amount of promotion, at least for day 1 kickstarter. I think this is probably backed up by the fall in both backers and pledges for almost a week afterwards, at which point it raises again no doubt due to some form of marketing.
Overall it just goes to show how important it can be to have a fan base for your product/company and that maintaining their respect can provide huge benefits such as seen here. I also suspect its the type of market that really plays up to fans and fan support, not to mention that board games themselves have been under going a revival of late and have always been popular.
Of course it should also be noted that whilst it is a large amount of pledge money, the basic game itself is costing $75 so its not exactly a cheap product so it would be expected that the money raised would be high.
