I made an all-secrets playthrough as example on this map:

Sadly the quality was butchered for the flash player but you can easily download the Ogg Theora original.
It is a shame H264 is patented, the quality is much better. Not to mention its adoption.
Also I wish I knew how to make Darkplaces' particles look like software Quake (colourwise, the weapon effects and blood). Oh, and that weird stuff on the left side of the HUD...
Anyways, any critic on this? Is the playing style alright? Settings ok? Texture filtering is a must for video compression.
