Clint pointed me a while back to Permanent Death, a free e-book/machinima/something from Ben Abraham narrating his experience in trying to play Far Car 2 through on a single life. In the author's words it is:
391 pages long and features hundreds of full colour screenshots from Far Cry 2, one of the most beautiful games of recent times. It chronicles my progress from the beginning of the game all the way to the end of my single in-game life some 20 play hours later. Permanent Death represents a large portion of a year of my life, and an obsession with a game that captured my imagination in a way that I struggle to articulate.
Clint's post on the experiment and book is also worth reading.
I found parts of it to be as monotonous as many games are (I ran into some guys. I hid behind cover and sniped them. then I scavenged their stuff. repeat). However, the parts of the game that were more moving to Ben are interesting, as are his thoughts about the game's rules and mechanics, his attempts to infer the designers intent at times, and his thoughts on things like switching off the background music.
Those and Clint's foreward make it worth reading. It's free, and it won't take you long, so what's keeping you?
