Well to be fair, the problem is not so much the PAD file idea (which is actually a good idea). The real crux of the matter, is there are so many low-traffic shareware sites around that aside from some of the bigger sites like Cnet and Tucows, there is no one particular site that's worth bothering with.
Even if you put your game on Cnet, you're thrown in amongst millions upon millions of other software titles and as a result, you're as good as invisible.
