Well, for (most) games i agree, but unless you are using .net and c# then development and 'art' isnt really an issue (c++, java, pascal, blitzmax, python, Photoshop, PSP, gimp, Maya, XSI, ac3d, blender, yak.yak.yak. and others can all work on a linux system)
Cross platform is cross platform and that goes for development too (except for the compiling of course, but thats vice versa :)
