The first point regarding release dates over quality of software is almost certainly true but by no means confined to DTG. I spent many years as a software tester (service delivery testing), testing the finished product immediately before release. This was not in a computer games company rather in the development of software releases for huge database systems. My team frequently got the code late due to overrunning development or problems found in system testing requiring further work. However, as far as I remember, a release date was never changed. The policy was to test what we could and release on a wing and a prayer, making fixes post release as necessary (which was nearly always).
