I preordered Age of Empires 2 HD on steam, as did many others. It became available to play and ever since then there have been masses of complaints from people about it crashing, bugging out or just plain not working. I myself am unable to play it as it won't even launch without crashing (apparently this is happening to anyone who tries to play it on xp or a 32-bit version of vista). Given that this is basically just an HD rerelease of an old game that worked fine, how have the developers managed to screw it up so badly?
EDIT: The system requirements specifically state it should work on xp.
