The DS has 2. FF3 and FF4. GBA had 1 through 6 minus 3, the Wii had VC ports. (I believe). 3ds has zero. When the 3ds came out it was a given that a remake of FF7 was going to be released. I am still waiting.
Japan got remakes of the Legend games for the DS those would have sold well in NA.
The FF7 remake would be the perfect last big game for the system.
I don't care for FF after FFX tbh. I haven't actually beat any FF named game. So it's not a big loss imo.
The only Square soft games i have beat are in this order: KH1 Kh1 FM KH2 Chrono Trigger
Squaresoft games I own: super mario RPG Chrono trigger (Ps1) Chrono cross FF4 (Ps1) FF 7 FF 8 FF 9 FF X FF Disidia (PS vita) Dungeon seige 3 BBS (PSP, Ps3) KH1 Chain of memories (GBA, Ps2, Ps3) KH 2 Kh 1.5 KH 2.5 Days RE: Cod Dream drop distance (3ds) The World Ends with You Bravery Default
My FC is 4957-4763-9094 (Pokemon Sun) PS3: hellfighter45 D3:UE, Xenoverse 1 PSN: hellfighter44 God Eater R (VITA), DB Xenoverse 2 (PS4), Rocket League
So why hasn't FF1 been ported to NA? They already translated it.
Most likely because their executives decided it wouldn't be financially worthwhile. They would have to submit it for an ESRB rating, which costs money (each new release of a game requires this, even if just a port from a previous platform, as the rating is per platform), plus whatever fees Nintendo has for listing it on the shop. It would have to sell a certain number of copies to break even on those costs, and then more to be profitable. If the game isn't expected to reach a certain level of profit, it isn't worth releasing.
Generally the reason every region doesn't get every game is financial as the root cause. They don't just blindly release things, they do a cost/benefit analysis first, and a sales projection.
We actually got more Dragon Quests instead of Final Fantasy.
And y'know what? That's pretty okay by me :). It's not like SE was absent from the 3DS lineup. KH, 2 Bravely games, 3 Dragon Quest games (plllleaaaaase may the we get the 3ds version localized....), Theatrhythm...decent amount of games from one studio. Japan got a few others as always, but we did okay.
The Japanese 3DS eShop has gotten FF1-3 for regular 3DS (and New 3DS, too, of course) and FF4-6 only for New 3DS models. Not sure if JPN 3DS got Final Fantasy USA: Mystic Quest, but I know JPN Wii U got it. The JPN Wii U eShop has FF1-6 plus Mystic Quest (I have a JPN Wii U, too).
As others have said, the JPN 3DS eShop has that FF1. I got that free when I got FF Explorers.
