User blog:The Sims fan/Only MySims for PC?

I have a question. If anybody knows the answer, please say it to me! Why are the EA making the SkyHeroes (and the other MySims games) for only Wii, and DS? I have only PC, but I like MySims Kingdom, Agents and SkyHeroes. Why should I buy a Wii (or a DS), if I want to play with them?
