Grimoire from World of Final Fantasy.
It's a mix of all great things and places of Final Fantasy. I can also be a mirage keeper, which means capturing my own hoard of Final Fantasy summons and enemies to power myself up and use at my leisure. I could
finally have a pet Malboro all my own and ride it wherever I go, and wage
biological warfare on anyone and everyone who tried to give me shit.
Or, I'd have a Mecha Chocobo to ride and go to any place I see fit, while raining death and destruction on my enemies.
Or even...An Ahriman. Those floating one-eyed monsters totally remind me of Mike Wazowski and are
fucking awesome. Those fuckers can hurl curses and confuse enemies
wonderfully and they're so ugly and freaky they end up looking adorable if you stare at them hard enough. I could ride ontop of one or let their lesser evolution ride on my head...
The only danger would be... The hoards of mirages and Cogna that would be there but hey. That's why you
catch them. And considering Grimoire houses Champions such as Cloud, Squall, Lightning, Tidus, Terra, Bartz etc... Whatever might threaten it would probably end up getting beaten back pretty quickly. Bahamutian Federation assholes might be a problem but hey. That's again, why you fight them with your mirages and not yourself.
Any world that let's you visit the Library of the Ancients, Midgar, Figaro Castle, Balamb Garden and Cornelia in the same world is a winner, hands down.
VIII's world gets special mention because it seems the safest and
least fucking insane.
Aside from the Moon occasionally shitting monsters onto the Earth (thanks in part to a nutbag Sorceress who wanted to weaponize the Lunar Cry), the world of FFVIII is relatively normal and analogous to the real world in its function, while also not completely being a threat to human life. Aside from the crazy Sorceress who tried to conquer the world and then fold all of space-time into a singularity within herself, the world was relatively peaceful and orderly. It's beautiful, diverse, friendly and hey... Being a SeeD mercenary pays pretty fucking well and lets you even keep your own pet Guardian Force!
As cool as most of the worlds of FF are, they're... Pretty fucking horrifyingly dangerous.
FFVII's world is
dead fucking last. I would never want to live in that world. Between Meteorfall, Geostigma, and groups of humans being rounded up and melted into pools of Lifestream... Yeah no.
I almost said FFXV's world but then I remembered the bullshit with the Nifelheim Empire, Starscourge, and god forbid I lived during the 10 years of eternal fucking night. Yeah, no thank you. I love Insomnia and think it would be an awesome city to live in buuuuuuuut we saw what happened to
that place
FFXIII's world is
second to last. It's a world where the main creator deity is fucking batshit insane, and his lesser gods actively hate you and want to use you up until you're a crystal zombie.
Sooooo yeah.
Grimoire it is. At least Enna Kros seems like a somewhat nice, if hands-off kinda god.
