Then Anakin would have never been freed from slavery and also would have become a professional speeder bike racer eventually winning his and his mother's freedom. They would have eventually raced against each other, Palpatine the experienced older established racer from the inner rims and Anakin the up and comer from the outer rims. It would be the most anticipated race in years.

Would Anakin even have existed? Because Plagueis created him along with Palpatine.
Anyway, I think he would still become a Force wielder. We saw how he lashed out at his family. It would only be a matter of time before that happened here. Then, he could very well become a Sith or seek out the Sith given he had some Sith stuff.
