Let's say you were suddenly in Eorzea...

[MagiusNecros]

Curse the Twelve knowing I'd be stuck doing noninteresting content. Or spice things up a bit, go back in time, side with Gaius, resurrect Zodiark for kicks and make the Garlean Empire take over ZA WARUDO. Beast Tribes will go extinct, Primals go away and all will be well.

Or go on adventures forever with GREG. Because he's a cool dude.

[Eul]

Sorta of "My dream come true" then. Having muscular body (Currently is decent ), living near beach, can craft anything, and so on.

[MeeDeggiThePunisher]

Go to the nearest town exit and test out my new BLM powers on low Lv mobs.

Punt the first Lalafell I see.

Then Fire IV that guy.

[TouchandFeel]

I'd prepare myself for the inevitable coming of the one true evil primal destined to bring about the death of adventurers everywhere... Netflix.
With how much time is spent preoccupied with and worshipping it by people, you know it's coming and your death (in duty finder) is assured.

1. Play with my thick long sturdy tail

2. Get thancred out on the town to pick up women

3. Master all forms of fighting then try to combine them into one

[AskaRay]

Unless I retain my character's abilities to survive and such

You would retain all your character's amazing traits and talents.

1) Change to Cul and Tastes all recipes from page 1 to master 2.
2) Grab Y'shtola tail
3) Kill Gerolt for sending us to gather atma
4) Kidnap nanamo and demand large sums of gill as ransom
5) Have fun with my retainers
6) Pay a visit to ser Aymeric and seduce him
7) Bribe PVP's staffs to get me the 200 wins record to get ADS mount immediately.

This is GTA right ?

Might as well be if we're gonna be in it lol. Ability to make change isn't something we actually had until noowwww > (if it were real )

[Kaiser-Ace]

you wouldn't know if you don't test it. the question is will you?

Honestly..... I'd assume I would be able to "return" after defeat and retain all the martial skills from leveling, then immediately head for Dravania for some Dragon slaying.

I'd find out the hard way to both questions eventually.

[Kahnom]

Don't forget to Flirt Garuda and Shiva.
Put lalafell in the barrel and roll them over the hill.
