I really love that developer commentary, as it was hard for me to understand his creative development process until I heard him talk about it. I only played part of one map before giving up (after I turned a corner several times and happened to run into a creeper spawner immediately each time... nope, too much of a fraidy cat for that!) but I adore watching people play through his videos. I'm quite excited to see this series, as I found Brian's videos through the fanserver's UHC and I love his style of commentating.
