With the cost of games going up and up, many gamers don't realize that a large part of what they are paying for is the packaging that comes with the game. Those fancy booklets push up the cost to the manufacturer and hence the price gamers are paying. There is good news though! For many titles you are now able to buy the game online and download it right to your Wii console ready to play. No trip to the shops required.
Many people automatically think that downloading games is illegal, but fortunately there are now many places online where you can pay to download games, music and films to your Wii completely legally. This form of distribution has been used for PCs for a long time with the steam platform for games, and services like iTunes for music. Consoles have lagged behind but are now beginning to catch up which is great news.
There have been predictions in the past that before long all games will be bought over the internet and downloaded straight to your PC or console. That time is still some way off, mainly due to internet speeds still not being reliably high enough for some people. However it is almost certain that in the future all games will be downloaded online, which is why console companies are starting to get in on the market now.
If you want Wii download free games, you may be out of luck however as most free download sites are illegal. There are many subscription based sites though that charge a small monthly fee in return for downloads, and these are a much better option. These same sites often also allow you to download movies, TV shows and more.
