What fun it is knocking-out my 7 year old. If nothing else, Wii Sports wets the appetite for more Wii-style control.
Tennis, Baseball, Bowling, Golf, and Boxing: boiled down to the basic elements, these quick diversions don't require a teen's share of freetime to get a handle on - you simply pick up a remote and play.
Gameplay
The Wii remote is pure genius. You simply cannot get this same experience playing any other console or PC. It is a simple and very enjoyable way to game, and it shines in Wii Sports. Bowling feels like you're at the lanes with a beer in your hand. I practically threw my arm out playing baseball, and I nearly broke a sweat boxing.
The gameplay is something you must try. Outstanding.
Graphics
They are clean and simple, and the graphical style is charming. My wife noted the obvious Asian roots to the graphical design being pleasant and light.
I've played PC games for several years, and to be honest, the graphics on the Wii titles I've played (which is certainly true for Wii Sports) cannot even compare to modern PC hardware (or XBox 360 / PSIII).
Sound
The audio is cheery and light. It is well composed and gives a nice compliment to the gameplay. The sound quality is good.
Value
The sports of Wii sports are not full on representations of the actual games. Baseball is pitch n' hit, Golf is 4 clubs, Boxing is a flurry of fists with very little strategy... The true value is the immediate fun-factor. After playing for awhile, I developed a thirst for more in depth play. This may have been Nintendo's intention - who knows.
Nevertheless, I see replay value in this title for years to come. It is based on simple competition between players, and that never seems to get too old. If my brother and I had one of these 20 years ago, I'd wager he'd still be up for a match today.
Tilt
I'm calling this an instant classic because it changes the way I think about video games. When I want to be alone with a gorgeous alternate reality, I'll hide out in the basement with my PC, but when I want to laugh with some friends and family, it's Wii Sports all the way.
