Is there any virtualization software that will play games i am running vista and have a compatibility issues and i want to virtualize XP

An extremely limited number of games can use 3D acceleration in Parallels and Sun VirtualBox for DirectX and OpenGL, respectively. I would recommend that you first attempt to use Vista's compatibility mode options first, as you wil likely receive better compatibility and performance anyway. To adjust the compatibility options, right-click the application or shortcut, select "Properties", and click the "Compatibility" tab.
