God!, the adventure game genre evolution is zero!  i don´t know why.
Years ago there was more ambitious adventures, "Lost  Express" was one...
the genre must go in a multiple paths way(i hope i explain me), more freedom, that the story evolutions  in result of your actions(and not, it wouldn´t  become a RPG) with multiple endings. This must a adventure game today, i think...       
it´s a shame....
