It depends, rarer games with limited releases trend up far more quickly. Some big examples of this are Earthbound and Phoenix Wright. Earthbound was expensive in most territories even during the time of its release largely due to it only being released in the US in English. Phoenix Wright nearly tripled in price just a few months after release because Capcom grossly underestimated its potential, and had a limited print of the game. Games like black label FF7 took a little while longer due to wider release.
I describe myself as a little dose of toxic masculinity.
