I am glad to announce that nQuake has finally reached Linux and Mac OS X. It started out as a small hack to make installing nQuake on Linux a bit smoother than running it through Wine. But as time went on, the installer grew more advanced. And as more time went on, it got ported to OS X (not much work since OS X is a UNIX operating system).
Sure, people might still want graphical installers for both Linux and Mac OS X (the users of the latter OS are probably more keen on seeing an installer with a GUI). But the bash script currently used is actually a lot faster than the GUI installer seen in Windows.
nQuake has entered a new era. Hopefully it will evolve even more as time goes by. Someone give me hints on how to create a GUI online installer for Mac OS X on the forums please :-).
