IN, MoF, and SA are the only Touhou games I would consider playing for score anyway, though as soon as you die, the score is screwed on MoF, Damn it Aya. PoFV too, but you have to play that for score otherwise you don't get enough extends to cover the 1 death minimum per stage starting at stage 6. I can't score worth crap in PoDD either, so I never get the second extend.
I wasn't even trying to score and got over 2.9 billion on IN. MoF is easy as hell to play for score. And if I was consistent at SA so that I'd be able to survive after all those suicides, I'd try, but as is I score higher just playing for survival.
