Thanks for asking... these are my neighbor's games... I'm a PlayStation guy and have no idea about XBOX. I don't want to mislead you, so hopefully you can find an XBOX expert to answer that for you. Thanks!
Red Dead Revolver is a western third-person shooter video game published by Rockstar Games and developed by Rockstar San Diego. My favorite game is Midnight Club 3 Dub which is made by Rock Star, so I expect it to be amazing.
It has the feel of a Spaghetti Western which allowed them to add more blood and over-the-top characters. The game reproduces a "grainy film" effect and uses music from various Spaghetti Western films. Hope this helps!
To answer Alex284's question: Backwards compatibility with XBOX games on the Xbox 360 is hit or miss. You're going to have to take a chance every time you try to play an original xbox game on the 360.
With that said - all original xbox games are supposed to work... (but most don't)
