Is there still an active custom mission "scene" for single-player missions?
 

The most recent files at subguru.com appear to be from 2007. Are there any other custom mission repositories for DW?

I like to think that I'm pretty good at creating custom missions of my own, but there is obviously very little to surprise me in a mission I've created myself, even if I use all the available randomization methods.

I recommend checking the downloads section of this site, as well as at CADC. Bill just hasn't been updating his site all that often anymore.

Obviously, the rate of missions being created is much lower now than it was in, say, 2005.
