Speaker recently announced over at q3w that he made a soundpack for game development.
I have made a sound package for game, mod and map developers. The present version contains about 740 sounds in 31 categories (separate folders, see the README below). The size of the archive is 129 MB, it can be downloaded here:
The sounds in this archive have been downloaded from the WEB site 'freesound.org'. They are distributed under the Creative Commons Sampling Plus 1.0 license. The license can be found here: http://creativecommons.org/licenses/sampling+/1.0/
