Grade is unaffected. It loses points, but still passes the D+ threshold (few games with complete DR's don't).
hum sorry but even if I'm all new to this website, I don't agree with the game rating.
I extensively played this game at 1280x1024 & played around several minutes with 1680x1050 setting, I have to say the disappearing object bug makes the game borderline unplayable. the game camera is quite weird to handle as it is (try to move around on a steep hill/mountain for example...)
with this bug enemies, which are hitting you, become invisible and you lose precious seconds while trying to move the camera with your character (because the camera is bound to the character)
the game having a very fast pace makes these seconds far too precious to lose ...
so the final rating seems a bit overrated to me considering the kind of flaw D games have in general...
In any case I just gave here my opinion, whether or not the rating is changed is not that important!
thanks for reading.
