Facebook games are gearing up for Valentine's Day with some surprising firsts in store. Extra special this year is that Rovio plans to bring Angry Birds to Facebook on that date. While we're not sure if Rovio will be sprucing up the launch with holiday appropriate themes (maybe they can bring in the Love Birds edition too), we do know that all the major Facebook games, such as FarmVille, CastleVille, and The Sims Social, won't miss the opportunity to sell players some virtual love.

To top it off, since The Sims Social debuted last fall, that means this year will be its first Valentine's Day. If there was ever a holiday made for the Sims, this day is it. With so much out there, we've rounded all the relevant posts into one place just so you can keep track of it all.
