Given that dancing men dressed as famous United States Presidents selling furniture in television ads on President's Day has become common place, video games going on sale on Valentine's day isn't really surprising.
Direct2Drive has done just that. They announced lower prices on
Assassin's Creed,
Prey,
Europa Universalis Complete,
Fallout 3 Game of the Year Edition and a few others. So if you're in the unique position of having a significant other who has invested a large chunk of change into a gaming PC, why not show them you care by
buying them a cheap game. Happy Valentine's Day!
