Parents shouldn't worry too much about Kinetica. There is some vehicular combat, but it's more bout bright explosions than gruesome bloodshed.
Fans of futuristic racers should stay home and continue to play the games they're fans of. There's nothing here that will make you put down F-Zero or WipEout.
People who aren't already tired of futuristic racers might be interested in picking this up cheap. It's a good introduction to the conventions of the genre.
People who aren't big fans of racing will find nothing to change their minds in Kinetica.
People who like staring at the behinds of people in full-body racing suits will enjoy this game to no end.
Deaf and Hard of Hearing gamers will miss out on some good sound effects, but should be able to play the game flawlessly.
