You can search Google for the phrase 'wii game downloads', and you will most definitely find thousands of results, but there are basically two types, free and paid membership downloads
Free downloads
The trouble with free sites, is that they usually have a slow downloading time, plenty of annoying pop up ads and a limited choice of games to choose from. In addition, you may be at risk to spyware and other malicious viruses.
Paid membership
Membership sites usually charge a one off fee, but this gives you access to a much larger database of not only games, but music, movies and TV shows too. Download speeds are much faster and you also receive unlimited access to download as much as you want. As a member you will also receive all the tools needed to transfer the games so you can play on your Wii right away, and online customer support if you have any trouble.
Like the saying goes, you get what you pay for and I personally believe that membership sites offer much better value.
One of the most exciting features of the Nintendo Wii is the ability to download Wii games from the internet, instead of having to go to a store each time you want to buy a new game, you can simply download Wii games online instead, allowing you to also download music, movies and so much more to your Nintendo Wii. Once you download them they are yours forever. So not only do you own a revolutionary game console which is the Nintendo Wii but now you can make it an even more powerful console with the websites available.
The good points about websites like these is, that you can download unlimited games, movies, music, films for a one off membership fee. Easy to use software that works with Windows, Mac, and the Nintendo Wii
With all the potential downloads available, it is now very possible to turn your console into a complete home entertainment system.
And finally...
-Make sure the service you join ensures safe and quality downloads
-Be sure you totally understand their fee structure if they have one
-Make sure using the service you join will not put you at legal risk
While I will agree it can seem like a bit of legwork to get yourself set up with a good quality download service, it really is a necessary precaution that needs to be taken for your own protection.
And, once you do decide, you will be very happy that you did your homework when you finally get your service set-up and see the unlimited possibilities available at your finger tips.
