They are old, but you can't go wrong with any of the final fantasies
Best ones are ff7, 8, 9, 10. Think now they are on number 6000....
And FF6 (FF3 in North America).
That shit is so nostalgic to play and still one of my favorites.
I love the final fantasy series. I like role playing games with hidden characters. I will get bored if a game doesn't have too many secrets. These days too many games outline what to do and where to go and there is little exploration.
It is one of the reasons I loved Lunar The Silver Star, secrets.
