Facebook's Fastest Growing Games FrontierVille leads the way by a mile By John Johnson, Newser Staff Posted Jul 10, 2010 3:59 PM CDT 2 comments Comments Frontierville is growing quickly on Facebook. (Flickr) (Newser) – AllFacebook runs down the 10 fastest growing Facebook games. Click here for the full list, or for a sampling: FrontierVille: By far. It added 3.7 million users this week alone; it's from Zynga, the maker of FarmVille, which is heavily pushing it. Millionaire City: It added 800,000 users to approach the 3 million mark. It's a little like Sim City. F IFA uperstars by EA Sports: It, too, added about 800,000 users, but will the growth last once World Cup fever ends? Verdonia by Playdom: It's a strategy game in the vein of "Kings of Camelot." (No figures given.) Baking Life by ZipZapPlay: It's one of those build-your-own-restaurant games, and 700,000 baking fans signed on.
