For me, the Wii has been the worst in terms of value. I loved Zelda and Metroid Prime 3, but in total, I've probably spent less time playing the all the games I have on the Wii then the time I've spent playing just Oblivion (or Pro Evo 2008, or Fallout 3 for that matter). And when it comes to old games, it not like the Wii has FFVII, MGS or any of the PS1 classics, not to mention the fact that I can play nearly all the old games on my PC (or my 4-yr old laptop for that matter).
I think for traditional games the Wii really isn't good value. My cousin (not a hardcore gamer) bought a Wii and sold it after a few months because he hated playing football games on it. If you want newer motion control based games then the Wii is very good value, but otherwise, the other consoles at there current price point are much better value.
