Sims are huge... duh!

Gamasutra has posted the sales data for PC games. Remember, these are PC game sales which I don't think inlcudes console sales (someone please correct me if I am wrong). Five of the 10 games are sims... because sims are traditionally as popular with girl gamers (if not more so) than for boys, I wonder if this speaks highly of the buying power of girls in games. If so, I am pleased that the gender gap is starting to narrow...
