I will defend P3 and 4--well, I liked them at least. I never went back to play 1 and 2, partially because Persona, regardless of the game, is LONG, and I didn't want to have to track down physical copies of really inferior versions of the game (especially US P1--good god I don't know what they thought was so wrong with all the characters!). Are there even PS1 ISOs for less awful English versions? I would honestly play fixed versions of the US editions, but I don't know if anyones hacked those, and I'm not buying a PSP.
Being quite honest here, Persona 2: Eternal Punishment's worst aspects are its voice acting (Most of the actors are union veterans by now.) and the fact that it kept the Revelations: Persona names. Persona 2: Innocent Sin was never brought over, so you'd have to use Gemini's translation for it.
As for Revelations, no, you're either stuck with the Americanized version or the PSP version. If you have a PS3 or a PS4 controller and appropriate charging wires, you can pick up a PlayStation TV for like $40, assuming you live in the US? Everything's on PlayStation Network. You wouldn't be able to play the original P3 FES or P4 on it, but you could get Persona 1, Persona 2: Innocent Sin, Persona 2: Eternal Punishment, (PSP port wasn't allowed to be brought over, so if you want it in English, you're pretty much stuck with the PSone version either way.) Persona 3 Portable, and Persona 4 Golden all on the same system.
I was trying to do a minor modernization update for Revelations: Persona; put in stuff like the current series standard of item and spell names, but it didn't pan out. So I'm trying to settle for a text cleanup... The script is surprisingly not that bad. When I first played it, I thought it was atrocious, but going back to it after playing Persona 1 Portable, it's actually pretty well-translated and decently written.
It's got a bunch of horrible typos, the names of spells, demons, Personas, and items were changed, and of course the Americanizations and graphical changes are there, but that's honestly it. The one thing you'll miss is when you meet Boy with Earring in Persona 2: Eternal Punishment. (He uses the Persona 1 protagonist's original design, but of course Revelations: Persona players wouldn't know who the hell he is due to the redesign.)
Revelations is like $70 used, disc only though. I wouldn't recommend getting it.
