Just like the question states:

"Persona 4 or Persona 4 Golden?

My situation:  I have a working PS2 and I have Persona 4 for the PS2.  Barely statred playing Persona 4.  I have NO PSVITA, but I have Persona 4 Golden because I love the Persona series.  I have the first Persona 4 Blu-ray release, but have only watched the first, like, 5 or 6 episodes.  Do I really need to bite the bullet to play the definitive Person 4 version on the VITA?  Help.  

Have you played persona 3? if so play that

I've only played 4 Golden.

It's got like an extra month or so on the end, extra s-links and tons of other extra stuff. I think it's the best way to play it

Besides, I'm sure you want to play the Persona 4 dancing game after

I'm playing Persona 4 Golden and thinking I should play 3 afterwards

But there's 3, FES and Portable to chose from... And you can't control your allies in Portable which would suck. I'm really confused

I am waiting for PS Vita TV. I will get persona 4 golden with it. Cant wait for persona 5 and persona 4 golden (in PS Vita TV).

FES is a much much much better game, if you were ever going to play persona 3, you would have to get that version. :)

FeMC is the best route, too bad P3P does not include The Answer

Really is no competition.

My favourite moments and music tracks in the game are additional Golden content. I can't really imagine the game without them.

That's the problem, I'm not really sure how to buy that. It's not on the EU PS store

I'll give you these suggestions:
-Close your eyes.
-Buy the Vita.
-Pop that sucker into your Vita.
-Enjoy life.

And if you want extra satisfaction out of your life, buy Persona 3 Portable digitally on your Vita and you are set for days...no weeks...no months...perhaps even years.
