We choose 1 or more source maps, and 1 or more goldsource maps, and everyone "take them home" to compile and report your compile times/system specs, all with the same compile settings, compiler, etc of course.
Might be fun to see how your computer ranks... we could list member name and computer specs and compile time, etc...
We also might just use 1 big map from each engine, or 1 small, medium, and large one from each to get more interesting info... i dunno, what do you think?
