Just released December 5th Mana Games has created a game for tennis fans called Tennis Elbow Mac. This is by far the best 2D tennis game for Mac, featuring both fun and realistic gameplay for both beginners and advanced players.
"With its ultra-realistic ball trajectories, an artificial intelligence that accurately replicates players’ behavior, and a complete range of strikes and game situations, Tennis Elbow Mac is the only game reproducing the impressions and the emotions of the player on the court with such realism."
Having five different surfaces to play on: clay, grass, hard, synthetic and indoor and five difficulty levels, this game is definitely a crowd pleaser!
