Wikipedia has nearly 1800 games listed for the wii. And although the system is probably the king of shovel ware, a person can put together a solid library of 50-100 of decent games with almost all of them being Wii exclusive.
For those interested, many of the games that got reprints got a full color disc instead of a partial colored disc like the original.
Reprint is on the left

This doesn't seem to affect the price either way though
Other notable reprint info.
Many reprints came from gamestop
There are also "refurbished copies" of games sold by Nintendo on ebay and their website. These don't come with the manual and have artwork that says refurbished across the top. The discs themselves are likely new because why would they bother resurfacing discs when they can just make more?
Xenoblade Chronicles original game in a case that has Wii molded above the disc and can be case swapped (Reprint did not have this, and they basically opened or didn't seal any of the copies and sold them as used at 90!)
Metroid Prime Trilogy - Original Came in a steel case.
Fire Emblem - Reprint did not come with manual, outside artwork is slightly different.
