Always awesome to hear about going through these older games!

Not sure if you started FFVI but I'd reiterate the GBA suggestion - the PSX load times are utterly horrible (be glad FFV didn't suffer from it), sorting your inventory and healing after battles is a big part of FFVI for me and the PS version ruins it. My personal favorite is the RPGOne fan translation. They made it a literal translation of the original Japanese script with some balancing to make it readable. If you read the notes in the Readme that come with the patch, it really was a work of art. Some things are better in the official localizations, for example one character says:

"I am _______. I am your worst nightmare." but literally translated is:

"I am ________, the _________ of __________. If compelled, I will forego my honor and engage you as a normal soldier!!!" Of course, the trade-off is you don't miss out on any of the adult themes, or the foul language that Square developers actually used a lot of...

When you get to the PlayStation generation of games, getting them digitally from the PlayStation Store is a great beat. They don't look all that great on a HDTV, but an SDTV is fine and they actually look pretty gorgeous on the PSP. Plus you can take your saves with you on the go.

Happy playing!
