Did I miss something (I've been off GAF a few days)? Why are you asking why now? Did something happen with a kickstarter or just so many in general or...?
I think he is just complaining about too many.
For "hype" projects recently there has been Double Fine, Wasteland 2, The Banner Saga has seen a lot of hype to it, and Shadowrun. (Edit: Forgot about Larry, how could I? Although it is moving fairly slow... much slower than I thought it would at least)
Although if you pledge 15 for each that is only the cost of 1 new game for 4 titles I suppose, but I will admit they are coming out at a pretty accelerated pace...
