When the credits rolled on Mario Tennis Aces' Adventure Mode, I vowed to never again laugh at a tennis player having an ugly meltdown on the court. I had felt the volcanic surge of adrenaline that comes when a rally has gone too long. I knew the sense of high alert while trying to suss out which corner of the court an opponent is going to attack next. I have spliced and invented new curse words to mutter when a ball goes out of bounds. Off-beat stages and creative use of characters from the Marioverse ensure that you'll never lose sight of simply having fun, but don't let the adorable exterior trick you; Aces takes its unorthodox tennis very seriously.
