Is it succeeding?[/quopte]
It is succeesing better than any other RPG.
If it is, is it as an amphibious beast, or despite it? How much more sucessful could it be if it became a true RPG, instead of the dual natured creature it is?
Considering that the less-amphibious beasts in the market sell poorly by comparison, one would not expect it to become more successful if it became what you call a "true RPG". The thing you seem to be missing, over and over, is that a great many people
enjoy the wargaming aspect.
