is it possible to play Xbox games on a PC

[mmace]

this has probably been asked a million times (and answered as well) but I have done a search both on these forums and the internet but cannot find an answer

can Xbox games be played on a decent PC (via an emulator or similar) or not?

if so, what software/hardware do I need?

Don't think that there is an emulator, however I guess someone in the XBox forum would know for sure, so I'll move this there now.
