I have volume 1, which Epic gave away a while ago. It's not bad, but it's not a game I'd dedicate much time to. When I was little, I was really into racing games, but then I lost interest.

I remember that in the early 2000s, I had a pretty fun Hot Wheels game on my Windows XP, though I don't remember if it was from this series or not, but it was good, haha.

I agree with you that it's a free game worth trying, but I wouldn't buy it.
