They just record peoples races and you race against their ghosts. The description made it sound as if you raced against people live.
That being said, this is free to play done right. Totally not necessary to purchase anything. You have limited runs, but can buy more with cash. Which youll always have.
Gameplay is addictive and fun. Controls work great. And youll want to unlock all the characters.
No end game stuff. And something to spend the millions of gold on that just piles up would be nice. But all in all, a really fun little game. Recommend.
