Straight from the pages of Wikipedia, compiled and edited by one Philipp Lenssen, this book tells the story of an era most people my age lived through and think back upon with great affection: the early period of computer adventure gaming. Companies like Sierra On-Line, Lucasarts, Microprose, and Adventure Soft defined the boundaries of what we now know of interactive storytelling, plot-driven game design, and narrative/item-based puzzles. It’s on sale at Amazon for $29, and is also available as a free, downloadable HTML file with “loads of screenshots”. YJSoon has a useful tip: run it through Calibre to make an EPUB file, and it’ll sit nicely on your iPad’s iBookshelf.
