A feature long-discussed and anticipated for Nintendo's Wii has been it's support for legacy games. The new system's “virtual console” feature, akin to many other modern consoles, allows games from older systems to be purchased and played on the new system. Unfortunately, in the past the price has often been a bit steep, as high as $25. Many people had issues with paying so much for software that was released decades ago with little or no change.
Nintendo has overcome this, and to get classic games onto the new console it will only run you from $4.50 to $8.99. This may result in the Wii having much more success with classic game use, on top of the games being downloadable via the Wii itself.
