Truth is, my first racing game experience was free and came in a Frosted Kellogg's cereal box.

For people who may not know what I'm talking about, it's this game:
Considering that the game is over 10 years old, and was free, from a $2.50 cereal box, it was surprisingly good. Hell, the AI was probably more intelligent than Codemasters' F1 2012.

My second game was another cheap but good one. Viper Racing.
A classic. Early childhood memories.;)
What are some of your first racing video games?
