I have greatly enjoyed my Wii (and still do)!
Wii gives the average gamer something new to look for. With a complete disregard for a standard in gaming, Nintendo have taken the first leap in what could be the real seventh generation in gaming.
The Wii remote breaks out of the box of simple controlling, as it takes complete advantage of the motion sensing technology, making playing the Wii a more interactive and active experience, stopping you from getting tired and bored quickly.
The small and sleek design allows you to store it anywhere you want, saving a lot of space. Nintendo weren't kidding when they told you it was small, because it really is! Comparing it to the sizes of the PS3 and 360, the Wii is far better for smaller spaces.
Graphically, the Wii produces crisp graphics (with the help of the composite cable - an excellent investment for people with HD TVs), much better of that of the GC or PS2 (some people still think the Wii has the same graphic capability of the PS2 - they're very wrong). While not amounting to the power capabilities of the PS3 or 360, the Wii is an excellent alternative.
The games list as of April 2007 is increasing, and more and more popular, 'un-childish' typcasted games are finding their way onto the shelves, releasing the Wii from the childish typcast. It makes the Wii far more appealing to the older generations, especially as they can look back to the 'good old days' with the virtual console, including games from a vast array of previous generation consoles.
The Wii is an excellent choice for all parts of the family, whether it be young or old, it is greatly appealing with games that suit all ages. It's cheap and greatly worth the £179.99 price tag.
I highly suggest you buy one! It's worth it! 5/5.
