Oh god.
Are you that narrow-minded that you think that the Wii's huge library of games can only carve out 4 games that aren't complete shovelware?, I can name around 20 other good Wii games off the top of my head.
In fact, I will..Just to prove my point.
Zelda: TP, Okami, Resident Evil 4, Resident Evil: The Umbrella Chronicles, Punch-Out!, HotD: Overkill, Little King's Story, Madworld, No More Heroes, Fire Emblem: RD, De Blob, Metroid Prime 3: Corruption, Boom Blox, Zack & Wiki, The Conduit, Klonoa, Final Fantasy: CC: EoT, Another Code: R, Rock Band 2, Final Fantasy Fables: Chocobo's Dungeon.
There, 20. And I could've named more.
And with a rich library of downloadable games from loads of great consoles and from WiiWare..You can not say that the Wii only has 4 games worth playing.
