I think you need to check your sources. Graphically, the entire game has been rebuilt from the ground up, and a whole ton of new content has been added. CS Wii is going to be a significant improvement over the standard free PC version.
Bayonetta and Darksiders are two recent examples.
Then there's FFVIII, Dragon Age, the COD games, the GTA games, Assassins Creed, ETC ETC ETC.
But Wii DID get Silent Hill: Shattered Memories, Dead Space Extraction, all the various amazing Nintendo games like Mario and Punch Out! and Fire Emblem, Little King's Story, A Boy and his Blob, Muramasa, Madworld, Zack & Wiki, Trauma Center, and on and on. Which is my whole point, the Wii doesn't get the OTHER consoles "Big name" shared titles, but it gets it's own collection of awesome games that nobody notices (and no other console gets(usually)) because they aren't in HD.
