Castlevania: Symphony of the Night
Castlevania: Symphony of the Night has two main versions that are played, the original PlayStation release and the Xbox 360 release. The Xbox 360 version has many notable improvements including far less game slowdown, at the cost of removing the ending theme, not being able to display the picture in 240p for display on a CRT, and minor changes throughout. The recommended version is the Xbox 360 release, but to experience it as intended, the original PlayStation version is a must.
