You don't need to install the GOTY. There is absolutely no difference between the games. The only difference is the installers.
Velerad93: Yes. But i no have 16DLC pack, Year version have this pack. I have the opportunity to install full version (all packs + 16DLC pack) But I do not know if I will lose my saves.
No, you won't lose your saves. They are stored in you documents folder. Provided you have the exact same version of the game and DLCs (and you're not using console version) then the save games are compatible.
