Xpert Eleven is an Online Football Manager game founded in 2003, acquired by Xpego AB in november 2011. The game is more casual in a way where the depth lies in choosing your strategy of how to build the team rather than trying to learn a lot of game functions. It's also one of the most social manager games since you can create your own league and invite your friends.
Over the years the original founder focused on optimizing the game engine, having the in-game currency balanced and building a game where players sticks around for many years. That they succeeded with. They didn't however focus as much on the user experience, getting new members or improving the social interactions between managers. This is why Xpego AB acquired the company.
