Hundreds of games for the original Xbox can be played on the Xbox 360, and they include most of the big-name offerings.
Some benefits come with playing your Xbox games on the Xbox 360. Besides the convenience of playing both systems’ games on one console, compatible Xbox games played on your 360 will be upscaled to 720p/1080i resolution, assuming you have an HDTV, and will take advantage of full-screen anti-aliasing.
However, backward compatibility also comes with limitations. When you play an Xbox game on the Xbox 360, the quality and the playability can vary.
