I get it! Thanks for your answers.

¡Hello! I bought the game some time ago and I realized that it comes with a free-suscriptor month, but I'm not sure yet if I'll pay it forerver. So my question is: have the preffered players the legacy system as an unlocked feature or I'll have to pay for it? And if the answer is "no", you lose all the previously gained characteristics of the family tree? ¡Ah! Another one: I know that the medical probes are reserved for the suscriptors, but you can pay for them too as F2P...is this a definitive unlock or just a pay for a bunch of them? Thanks for your answer.
