NPD has released its monthly list of the top 20 PC games, and while Star Trek Online made a valiant showing in the month of its debut, landing at number two for the main game and number four for the collector's edition, it was beaten in the end by the Sims 3: High End Loft Stuff (yes, "Stuff") content pack. The Sims juggernaut of a brand continued to rock the top 20, claiming six spots total, and perennial favorite World of Warcraft continued to place almost all of its current editions on the list in three different spots.

Other big titles in February were Bioshock 2, the Everquest II: Sentinel's Fate expansion, and Mass Effect 2. Aliens vs. Predator appeared at a miserable number 19, below something called the Mumbo Jumbo Assortment. Full list after the break. We'll say this about PC game players: They know what they like, and they stick with it.
