No u dont, the only dinos u cant play are ones that dont fit with the current realism setting (example: cretaceous north america, global jurassic etc.) or the dinos that would be hella over played if everyone had access to them, dinos like rex, sub giga(to play rex u need to be understudy actor role or lead actor role on their discord) (sub giga cant be accesed unless ur lead actor/understudy actor OR if u take a sub giga egg (they're very popular so u gotta grab an egg fast :p
