That doesn't really make a difference though, does it? The community has shown at every opportunity that it loves being able to hack with game software. A small group of volunteers has even completely rebuilt Morrowind from SCRATCH! Even if the original code sucks, I think people would love to be able to hack it, port it, and play with it. This sort of activity can only lead to increased sales for original publisher, who otherwise would never get anything after their game falls into obscurity.
