The entire series of FFXIII are honestly not bad games at all. Solid 8/10 for me. I wouldn't mind replaying them again if they remaster them to PS4/PS5.
Btw. FFXV is a fantastic game, just make sure you get the Royal Edition that has all the DLC as it will give more indepth to the story. Personally FFXV has an amazing story, characters, concepts, design etc...but could've been better executed.
