Do not underestimate the power of the game Deer Hunter
Beta releases of software aren’t expected to be perfect, but to be effective at gathering feedback, at least a basic amount of functionality has to work - otherwise no one will use it for long enough to find the undiscovered problems. Microsoft is currently preparing Service Pack 2 for Windows XP. This is a bit more important than their usual service packs because it will most likely be the only client OS release between now and Longhorn, which is probably at least 2 years away. So the beta of XP SP2 needs to be good. For example, Deer Hunter 4 needs to work.
