The month started on a Saturday this year, with a bevy of weekend Saturday April Foolishness. However, the following week it was back to business as usual--which, if you were a seller of PC games, would mean moving a lot of copies of Elder Scrolls IV: Oblivion.

Yes, for the second week in a row, Bethesda's popular role-playing game dominated the PC charts. Once again, it outpaced longtime champ World of Warcraft, which remained in the number two slot. Right behind it were two other now-perennial members of the PC top 10: The Sims 2 (fourth) and The Sims 2: Open for Business (third).

Real-time strategy was also well represented on this week's PC charts. LucasArts' Star Wars: Empire at War stayed steady at number five, just ahead of Microsoft's resurgent Age of Empires III, which jumped from 10th to sixth place.

The week's other top RTS was Electronic Arts' Lord of the Rings: Battle For Middle-earth II. It came in eighth, just ahead of another film-inspired EA title, The Godfather, and EA's original shooter Battlefield 2. Last but not least was 2K Games' Civilization IV at number 10.
