Marketers gonna market. If “simulation” is a hot-selling category, then games are going to be sold as “simulations” if they bear even a slight resemblance to an actual simulation. This the same industry in which the customers con themselves into thinking that Final Fantasy is still a role-playing game.
You can play most of it solo, aside from some of the major boss fights, and it’s both a “greatest hits” nostalgia trip and a damned good FF in its own right once you get into the Heavensward expansion and beyond.
