I would like to suggest that the media files for warzone2100 be installable as a package, perhaps at the behest of an optional use flag in the game's base ebuild that could specify the desired resolution Reproducible: Always
For clarity the files are expected to be present by the game itself which directs the user to fetch them from wz2100.net if they're not already there. Presumably wz2100.net could be considered the upstream source for sequences.wz
