Realistic Water Reflections

[Shougun]

Graphics and game mechanics do not have to have the same depth of realism.

SE has always tried to have a high visual realism for a high fantasy style; however, they seldom pay attention to realistic mechanics.

I think more succinctly you could say they work hard for their visuals to be "in another dimension plausible" and that realm has its own mechanics that do not always refer back to ours.
