Empire: Total War dominated last week's PC sales charts. This week? It's reign continues, as it tops the NPD retail charts and hangs onto second place in both the Steam and Direct2Drive lists.
Sales and expansion packs helped keep it from being a Total War clean sweep, though, as Red Alert 3: Uprising and Unreal Tournament III: Black both had strong weeks.
