I completely disagree with RMS and the GNU Project when they say art in
games, or art in general, is non-functional data and thus doesn't need to be
free.
Art, specially when used in games and other kinds of software, is rarely
non-functional. Art is not just about prettiness it's about directing the
person in her interactions with the software.
Also, let's suppose I design and develop lovable 2D/3D characters and worlds
that can be used and reused in games and stories. Wouldn't it be better for
all of us if I release them as a free cultural works? People could create
games with stories that I would have never think about. With non-free art, it
just stays with the person who created it and we have to wait ~70 years after
her death to be able to use it freely (if she had no descendants).
Since I found out the freedom exception for art, I don't consider GNU nor
free software distributions really free.
