+It's a separate version of the game which can be installed and played alongside
+the standard game, not a loadable mod (NewGRF, script, or so on).
+
+This is mainly intended to be used by players who are already familiar with the
+standard game and how to play it.  It is not aimed at beginner/novice players.
+Some features and settings are there for very experienced players and so may
+have a steep learning curve.")))
