New boxing and race car driving games add thrills and heated competition to the gaming experience. NY1's Adam Balkin filed the following report.

As the Sims franchise hits the racetrack in "MySims Racing," the new game is of course highly customizable, from choosing the driver to all aspects of the racing vehicle, from the body all the way down to the side view mirrors.

The more a player zips around the exotic locations of Speedville, he or she earns more access to parts to make the car look cooler and run much faster.

But being the fastest isn't always the key to success. Players use wacky power-ups, from throwing soccer balls to kisses at opponents, which can aid or wreck a racer's winning chances.

"MySims Racing" also has multi-player mode for up to four players, and gamers can save their cars to the Wii-mote, so they don't have to start from scratch if they're playing at a friend's house.

Rated "E" for Everyone, "MySims Racing" is coming out for the Wii and the DS handheld for between $30 to $40.

For more mature battling, developers of "Fight Night Round 4" are offering more true-to-life graphics in their boxing game, which make punches look as they do in the actual ring. Gamers can also play with legendary boxers, ranging from Manny Pacquiao to Mike Tyson and Muhammad Ali, who box in their famous styles.

A new "Legacy Mode" also lets gamers train an amateur from the very beginning up through his big title fight.

The game's ultimate "rubbing-it-in" feature is the ability to replay, from seemingly endless angles, that devastating blow that knocks the opponent, or their own boxer, down to the canvas.

"Fight Night Round 4" is rated "T" for Teens and comes out this week on PS3 and Xbox 360 for about $60.
