I've been recording video playthrough's of a fair few q1sp maps over the last few weeks and putting them on the yt at

I'll be adding more and more when I get the time, I want to get all the "classics" in there as well as videoing new releases.
Apologies for run quality of some of the earlier videos, I was doing them blind with fraps recording while I was playing which turns out pretty bad, ie lots of getting lost and derp moments. Now I've started running the maps through once or twice before recording and on the actual run I've been recording a demo and then frapsing that instead.
I've been considering adding minor commentary to videos also, so I wanted to know what kind of stuff would be interesting to listen to while watching the run. As a mapper I would probably talk most about the design of the maps and gameplay etc but I'm not sure it would be interesting enough. if you have any ideas let me know :)
