Having glanced around some of the problems people are having in the bug reports section, eg:
-corrupt licence files
-out of date playlists (eg wma instead of mp3 when upgrading to a HQ version)
-general corruption of settings/files in the Bliss directory
...it seems that a certain number of these could be prevented by having a "Clean Install" mode that removes existing versions of Bliss (eg: the game folder, the playlists etc) that could be used as a first port of call if people are having issues with the game.
What do you think?
