" This is one of those cases where I’m loving the iPhone work with the classic games because it gives me some real solid ammunition for the first time on the tangible benefits of what we as a company get from having released the source code for our games all those years ago. I have always had to make the argument that we get good will and there are intangible benefits. With both Wolfenstein 3D Classic and Doom Classic for the iPhone, instead of going to find the original source code, resurrect it, and make it compile on an auto compiler, I was able to start with this well maintained cross-platform source code base that people have been improving for years." - Marcel Weiß
