Irrational’s blog takes great joys in pulling out various bits and bobs from the cupboards and doing a show-and-tell. Latest is the original early-00s Bioshock Pitch. They’re serializing it across several entries but you can follow the first eight pages here. And it’s nifty stuff, in noting what remained (a lot, conceptually) and what changed (almost everything, in terms of specific execution). This stuff is always fascinating. And while we’re on the topic, you’ve read Planescape’s Vision Statement, yes? More developers should totally release this stuff. It’s absolute treasure.
