Wii Play

If you were asked what the best selling game on Wii is, you might think of Mario Galaxy, Wii Fit or Super Smash Bros. Brawl. You may be surprised to learn that it's actually a collection of 9 mediocre mini-games. The game is Wii Play.
If you don't already know, the reason for Wii Play's success is its value for money. It is such good value for money because the game come bundled with a Wii Remote.
nOf course the Wii comes with one controller but most owners will at some stage want to play multiplayer games. The multiplayer aspect of the Wii is one of the main ways the system is promoted. Just look at any of the adverts for Wii games. They always show a family or group of friends having a fun time together on the Wii. They never depict the man playing Zelda until the early hours who looks drained as he's been playing the game for 8 hours straight, yet feels determined to finish "just one more dungeon" before bed. That is another side of the Wii, but Nintendo focus their marketing on having fun together.
nSince a second controller is required to get the most out of the console, most Wii owners will want to purchase one. Wii Remotes typically cost between £26.99 and £29.99. Wii Play with Wii Remote costs around £28. So in some cases you can actually buy it for less than the Wii remote alone. At most you will not pay more than a few extra pounds for Wii Play than you would for the controller alone.
nThe downside of Wii Play is that the mini-games themselves are very shallow and likely to become boring and repetitive quickly. After each game has been unlocked, which can usually been done within two attempts at the previous game, there are no rewards for continued play other than a high score. If some of the games were a little more difficult to unlock, it could add further value to the title.
nWii Play is almost a free title given away with a Wii Remote so you needn't think too hard about whether or not to purchase it. Just don't expect the game itself to keep you entertained for more than a few hours.
