The only game made based on the characters from the Aim For The Ace movie and OAV series.
As you'd expect from it's source material the Ace Wo Nerae! game is a tennis sim, featuring the characters from the anime.
Despite being an anime license this game is actually quite a solid sports title with quite a few options and play modes. The controls are pretty simple but the erratic, wobbly camera shakes around worse than NYPD Blue which would probably give you a head ache after too long!
There is a fixed camera mode too but using this makes the sprites really small which, in turn, makes successfully hitting the ball a lot trickier.
Not a bad game but tennis fans would be better off sticking to a dedicated tennis game.
