Kickstarted board games are almost exclusively preorders for the game. So it didn't "need" to raise that money -- in fact it looks like their original target was about $33k.

It's an interesting question about fairness to consumers. Honestly I don't know that fairness is relevant here, as the Kickstarter boardgame scene is thriving -- many new board games exist through kickstarter than would otherwise exist in the world, and the consumers know this and participate in the ecosystem. If the kickstarter was limited to raising money for development costs then it's not clear that the producers would be quite as incentivized to put projects up there.
