Frederick I, the 1st King of Prussia (Frederick III of Brandenberg) had only 1 surviving son, Frederick William; his 2nd wife, Sophia Charlotte, lived apart from him after a few years and didn't seem to love him as much as he loved her.
So, let's say that Frederick William dies early (he did have porphyria and a violent temper which one could imagine leading to death if not an immediate cause), and the Queen of Prussia isn't interested in trying to have another child. What happens when Frederick I dies in 1713? He has a nephew (also named Frederick William, he of Brandenburg-Schwedt) but his nephew will be a minor for several years yet; would Prussia continue as a kingdom? Given his longer life (if he succeeds in 1713 and lives as OTL, he'd live to 1771)does this alternate Frederick William accomplish things similar to OTL's Frederick the Great? Wikipedia says he was very big on being active but also known for being brutal and short-tempered - so it's also possible he could get involved in wars before Prussia is ready and damage it quite a bit.
