"Non-U.S. Release" a U.S. Release?

[digitalpress]

Area 51, by Midway, is listed as a "non-U.S. release" for the Xbox, having only been released on the Xbox in Europe. However, I bought a copy here in Jacksonville at Game Stop, in NTSC format, that plays perfectly on my U.S. Xbox. What gives? Was it released here, or not?

My Sega Master System plays games released anywhere in the world, but it was designed to. Was the Xbox?

We're still waiting for a big update to the original XBox section. Area 51 was most certainly released in the US, it's a very common title, in fact.
