Zeal Islands (Chrono Trigger)
El Nido Archipelago (Chrono Cross)
Zanarkand (FFX)
Cleyra (FFIX)
Western Keep (FFI)
Costa Del Sol (FFVII, or maybe even the real place in Spain)
Chozo Artifact Temple (Metroid Prime)
Torvus Bog, Sanctuary Fortress (Metroid Prime)
Brinstar (assorted Metroid games)

Of course, bad things happen to quite a few of these places, so without those threats I would to live in any of them.
