I need a Web Application that interacts with multiple popular video games by way of API's to track, analyze/store, and compare player statistics. Essentially, it needs to be a "one-stop" place to track all your statistics for games the player plays that we support (have API's). Furthermore, data must be very secure because we pay people real money based on their performance (like a tournament). Please pick the best tools for my needs. It will primarily require database design, creation, and management.
