I don't get how anyone could think this is a bad idea.
1) There is someone with a proven track record for making mostly good games, but due to Hollywoodisation of the games industry and perceived niche appeal of adventure games he is unable to find a publisher for what could be a good idea for another good game. If this someone can use Kickstarter to be financed directly by the public isn't it kind of up to them what they spend their money on?
2) So what if they've surpassed their budget, they haven't started designing the game yet so it doesn't take a genius to re-route cashflow into different aspects of the game. Better soundtracks and voice acting
3) All this talk of piracy is missing the point - that will happen anyway! It's like turning up at a PTA meeting and saying "paedophilia is bad!" Well strawberry float me
