I see your point.  I figured that the nature of games made them less
important with respect to this type of security risk.  Reusing the games
user also makes the user management issues with the packaging much
simpler (no fedora-useradd registration or dynamic userid with useradd).

There's also the option of using selinux policies to make things more
secure.  This should probably be done regardless of whether the daemons
run under a single userid or separate ones.

Fair enough.  Some of the executables will still have to be setgid
'games' to that users can write to the shared scoreboard file.  I don't
think it would be reasonable to tell admins that they have to add users
to the 'games' group just for this purpose, especially when there might
be many users.
