Comment 2 for bug 1816377

#1 This means that when staring a new game, the player will always have to navigate to the "official" directory before starting to play a new game. Also, how will the installer recognize that an official map has been updated? Do we want to replace them without prompt/install a copy/... handle this on Linux/Windows?

If your motivation is the size, maps are not the big offenders:

tribes: (248.1 MB on disk)
music: (101.1 MB on disk)
maps: (20.6 MB on disk)
