For World Of Goo there is an rpm too, looks like if both packages are generated from the run installers (when it would have been compiled then the dates/sizes of the binaris would not be the same). The deb looks like created with dpkg-deb, but thats ok for this purpose, others do the same like teamviewer or softmaker. So why not create packages for the rest?
That is interesting since now they're up to ~40,000 contributions and the distribution is still about the same (possibly a % or more shifted into linux). That means there's been almost 10k contributions from linux. I'll be adding mine tomorrow.
