If you don't know, Wii Ware will be coming to the Wii soon. It is a way for software developers to create new games for the Wii that are downloadable. This is similar to the Virtual Console, but Wii Ware games are new ones that didn't come out with any console.
Recent news on the Wii Ware states that the maximum size of each of these games will be 40 MB. This is a little more than what we've seen for Virtual Console games which top out at 32 MB.
There are already plenty of titles coming out already which include 35 from Nintendo and 65 from third parties. Nintendo will only let a developer publish 1 game a month.
A big problem for people will be storying all these games now. The Wii only comes with 512 MB onboard storage. You can try using a bunch of SD cards, but it is still a hassle. Maybe a harddrive will come out soon!
