For those who have launch problems, go into the files and click on Launcher. Configure your controller and graphics how you wish, and then launch the game normally, but when it asks to make changes, always click "No" after initial setup, or it will reset your hardware configuration.
Other than that oddly specific launch problem, it is a VERY fun racing game with a bunch of SEGA's iconic faces and some crazy crossovers like Wreck it Ralph, Danica Patrick, Football Manager, and Team Fortress! Would highly recommend to any racing game and/or SEGA fan... or if you've ever wanted to see the Team Fortress characters in a racing game lol

its rather fun. difficult,challenging sure, but it makes you feel like you wanna keep on going. plus,team fortress is there. so hell yeah

The most fun kart racing game out there. Playing the Grand Prix mode locally with upto three friends (4 players) is an absolute blast. No game comes even close, people would argue Mario Kart is better, but that's not on Windows, so there's that.
Highly recommended, 10/10!
