An inverted look option is DEFINATLY needed here!!!!!
Other than that, this port is smooth as possible, was easier to get up and running than the Dreamcast version too.
As for the musick, I don't miss it, though I wonder if it would be possible to add in a feature that would take advantage of the tracks you have ripped form your own CD's, this would be a good feature for DOOMX and Quake X as well, though unimportant...
