Those aren't really worth getting a machine for. The only thing worth playing on Wii is Zelda imo. I'm not a hardcore gamer, and I don't like the shoot-em-up type of games you find on Xbox ... I like games from Civilization, to Monkey Island, to Lemmings, to Ultima, to SimCity, to Tetris. In other words, I like fun games. Not hardcore, just fun.
The Sims is a nice concept game, but it gets incredibly boring after playing it for a couple of days days. Really really boring.
