The Xbox 360 came out a little over 11 years ago, and to this day there have not been any fully fledged emulators developed to emulate all the great games that exist on the Xbox 360. This is due to the Xbox 360 (and PS3) both using PowerPC architecture, which is different from the x86 architecture 90% of modern PC’s use. In fact, even Microsoft thought it would be difficult to accomplish emulation on the Xbox One, which uses the same x86 architecture as PC.
With Microsoft’s breakthrough of emulation on Xbox One also came Xenia, a free and open source emulator for PC. As of right now, Xenia can play 50 Xbox 360 games at full speed, meaning that it fully utilizes the PC’s resources. Most of these games have been Arcade titles, but a few notables include Dragonball Z: Ultimate Tenkaichi, Rayman Legends, Ninja Storm Revolution and both Dragonball: Raging Blast titles.
Other games like Dead Space have been reported to run, but still need time to be fully playable.

I think this emulator has great potential, and it may give us PC gamers a chance to play all the console exclusives we missed out on. If you would like to check out the emulator, click here. Keep in mind that this is a work in progress, so not too many games work right now. Cheers!
