We love building synchronous, intuitive and clean interfaces.
We also love League of Legends. In the pre-game loading screen, websites such as LOLKing and LOLNexus allow you to see stats about your opponent, but do not show how good of an opponent they are. We aggregate and visualize statistics designed to help the user better understand how he or she wins or loses games, and how he/she can win in the current game.
League of Legends gamers (all 20+ Million of them)
clean interface, simple user interaction, smoothness, data aggregation and long-term tracking beyond what you can find elsewhere.
