It’s not the greatest arcade racer out there and without online, much of the content is permanently locked off.

I can highly recommend Sonic & All Stars Racing Transformed instead. Bit of a mouthful, but the game is fantastic. Very beginner-friendly, yet with enormous depth (easy to learn, hard to master and all that), fantastic driving physics and track design, excellent progression, tons to discover and unlock. Both single- and multiplayer are among the best in the genre. It’s also cheap (Steam keys are currently on sale at 2game for less than five bucks) and runs on a toaster, despite its excellent presentation (the blurry screenshots on the store page do not do it justice).
