12 is good, but it doesn't hold a candle to 10 and prior.
12's pace, voice acting, dialogues and even the combat are all amazing. The story itself is also great. Some of the characters don't have very interesting backgrounds but it's definitely one of the good Final fantasy games.
You should give 15 a go. The combat might not blow you away but the characters are all pretty good and their friendship, leading all the way to the end has some twists that you might not expect. The story isn't bad either but they screwed up by having it split into movies, game, DLC. And well, you can snatch it for PS4 for like 15 bucks so it's not all that expensive anymore.
FF7:R has my interest, but probably moreso due to nastalgia. It feels more like a battle to hold onto my beloved original, rather than trying to embrace this new vision. Gotta see more before I can begin to parse my thoughts on it.
The best thing about it, and a thing that everyone appears to overlook is that you don't need to fight that battle. You can get the remake and enjoy it, you can keep the original and enjoy it. It's a new take on FF7, not a replacement. The original will always be there for you. Available pretty much on any console, tablet, phone. I'm sure you could even get it on some of Samsung's fridges if you really wanted it.
This is why I don't get the whole crying and moaning about the remake. Don't like it? Great. The original is there for you and will always be.
