I think we all know Skyward Sword, for me, would go at #1 for the best game on the Wii, but as for Twilight Princess, it wouldn't crack my Top 10, and probably not even Top 20. It's possible it would be in my Top 25, but I don't know for sure. Either way, though, they're both great games.
By the way, here's my Top 5 Best Wii Games list.
5.) Super Smash Bros. Brawl
4.) Donkey Kong Country Returns
3.) Metroid Prime Trilogy
2.) Super Mario Galaxy 2
1.) Skyward Sword
I think that it's absolutely fair to place both Zelda Wii games in the top 5 Wii games ever (even though Twilight Princess isn't really a Wii game and thus shouldn't belong in this list) because they are both great games. But my top 5 Wii games list would look like this:
5) Super Smash Bros. Brawl and Metroid Prime Trilogy tied
4) Super Mario Galaxy and Super Mario Galaxy 2 tied
3) Super Paper Mario
2) Skyward Sword
1) Twilight Princess
This is very interesting! my list would have Twilight Princess on top and maybe Skyward Sword would make my top 10. I am being honest here, it isn't my favorite Zelda game, but i still love to play it every now and then.
My favorite Wii games are:
1. Skyward Sword
2. Donkey Kong Country Returns
3. Twilight Princess
4. Super Mario Galaxy
5. Super Paper Mario
It's rare for me to like any non-Zelda games more than a Zelda game, but DKCR was just awesome. That series was my favorite growing up before I started playing Zelda, and Returns does the earlier games justice.
