Say what you will about the average quality of WiiWare releases, these titles are a part of the Wii's legacy, one that is slowly being locked out to those who would want to experience them in the future. It's also rather disappointing that the many unique titles released on WiiWare can no longer be legally purchased by users. Users with unscrubbed Wii discs can rely on them as well to install the System Menu after they go down, but, depending on when the game was released, it may not be fully updated. Dolphin relies on the NUS servers for installing a fully updated Wii System Menu in Dolphin.
More distressingly, it's likely only a matter of time before the Wii Nintendo Update Servers (NUS) themselves go down.
