   message: <<EOM
-    OpenTTD requires the original Windows version of "Transport Tycoon
-    Deluxe" data files in order to function.  Copy the following files
-    to %%DATADIR%%/data/ (or better, $HOME/.openttd/data/)
-    directory:
+    OpenTTD can use free (libre) data files, split into OpenGFX for
+    graphics, OpenSFX for sounds, and OpenMSX for music; it will offer
+    to download them upon running the program.  Alternatively, they
+    can be installed as corresponding `games/opengfx', `games/opensfx',
+    and `games/openmsx' ports or packages.
+
+    If you'd rather use data files from the original Windows version
+    of ``Transport Tycoon Deluxe'', copy the following files to your
+    $HOME/.openttd/data directory:
 
 	sample.cat
 	trg1r.grf
 	trgcr.grf
 	trghr.grf
 	trgir.grf
 	trgtr.grf
 
     If you want the TTD music, copy the gm/ folder from the Windows
     version of TTD to your OpenTTD folder (not your data folder).  The
     music from the DOS version does not work.
 
-    Alternatively, you can use free data files, split into OpenGFX for
-    graphics, OpenSFX for sounds, and OpenMSX for music.  They can be
-    installed from corresponding `games/opengfx', `games/opensfx', and
-   `games/openmsx' ports.
-
     If you are using a non-Latin language, you may see lots of `?'s on
     the screen.  Please open your configuration file and add desired
     fonts (file name with full path).  Bold fonts might look better:
 
 	[misc]
 	small_font =
 	medium_font =
 	large_font =
 
     Enjoy!!
