The best start you can get on a Wii, one of the finest party games!
The game does not features any kind of story mode nor anything else, but it keeps track of your experience points until you reach the "pro" level with 1000 experience points. There are also some variations to keep you entertained.
So I'll take out of the way the more obvious details first.
The graphics are clean with very nice details, and, in general, get the job very well done. The characters are the same as any Mii an so that's all you can expect from them.
About the sound, that's a real good deal, as the general environmental sounds are just fine, but the real great addition are the wiimote sounds, as they really make you turn up all the volume in your remote to hear the swinging, hits, etc.
Ok, now for the sports:
Tenis is really a no brainer when coming to try out the Wii's capabilities. You don't need to move your character but you have very great control over the raquet itself. Soon, you can start making some great moves and, depending on your partners abilities, the game can become very long and exciting! You can play from 1 to 4 players and even request the CPU to assign you a partner in case you want some help. No button press is required at all! My 2nd personal favorite from the package.
Baseball can be a bit harder as it requires much more precision to hit correctly the ball, but as you get more practice you can turn almost any ball in Home Run, which is very rewarding! In the other hand, when you pitch there are several things you can do to make things a little more interesting, as each button (A, B, A+B) can turn your ball into a curve, splitter or screwball. 1 to 2 players.
Bowling is, for much, one of the greatest games included. The control you have over the ball is really amazing, and you can instantly start doing some great tricks adding effects to the ball. This also requires a little more explaining as you need to manage some buttons and the D-pad to ensure you get the most out of the game. 1 to 4 players and my 3rd personal favorite along with Golf.
Golf, as you can expect, makes a great use of the wiimote to simulate a golf club. You have 9 full holes ranging from beginners to expert courses, and the game also requires A button and the use of the D-pad to adjust your position. 1 to 4 players and this shares the 3rd position in my favorites list.
Boxing is the only game which requires both, a wiimote and a nunchuk for each player, as they simulate both hands of the player. No button is required and it'll give you a hell of a workout! The game itself is very exciting, although the controls may seem a little bit unresponsive at times. As you progress in the sport you'll take notice of the best position to grab the controllers to ensure best response. 1 to 2 players and my personal number 1 favorite of the package!
Finally, the game also features a fitness test wich you can take just one time a day and it will determine your phisical age using several sports. There are, also, several "challenge" modes for each sport that allow you to try variations of each sport to improve speed, accuracy, etc.
Overall, this has been my opening card in each "demo party" I've had and they had been great fun for everyone!! You may also enjoy a lot playing alone but don't miss the chance to play it with friends and family!
