Magnate Interactive

SmallWorlds, a "The Sims"-like game which appears to be a Flex application using Papervision 3D (or some other 3D library), is in open beta. The avatar creator is similar to the Mii creator on Nintendo's Wii. The site talks about having a developer API for creating Flash games. All in all it looks pretty promising.
