[quote name='Chris in Cali']Which sucks for me because some of my favorite Xbox games include Shenmue II, Pirates: Legend of Black Cat, Panzer Dragoon Orta, Elder Scrolls III: Morrowind GOTY, Serious Sam, and Enclave.[/QUOTE]
Don't be surprised if these are supported in time. The 'best selling' is more marketing rhetoric than priority. Sure, they'll start with Halo 2 but every time a game is certified as running correctly this greatly increases the chances of many other game running as the emulator becomes more complete and handles a wider range of developer's techniques for accessing the hardware. The bigger problem is the time required for the testing. A favorite but low selling game might be perfectly capable of running but isn't certified because they haven't gotten around to it yet. This leaves the question of whether consumers will be allowed to attempt running any Xbox software and report the results to Microsoft, thus speeding up the process, or if the emulator will reject anything not found on its list of certified titles.
If the former, a low selling game might get moved to the front of the testing schedule if it is widely reported to work properly.
