I'm thinking that 150$ tier will be helping here. The 'big' projects showed there's enough people out there willing to shell out a larger sum with the right incentive (if they're not broke yet that is... thanks, KS craze).
Apart from the regular stuff, boxed Collectors Edition etc. there's 5 adventure games, 4 casual games and two novels here. That's a lot of (immediately available I presume?) content. That could get people interested.
BTW, the average pledge per backer at the moment is over 200$
Wonder if Tex will beat out Jane in the "backer generousness" level.
