Please.
Final Fantasy 7 Remake is a pipe dream. We are getting a pipe dream. Some folks are worked up over it like its an ugly divorce. The game moved to a different medium and thus requires a lot more work and a lot more budget and a lot more things to do. Do you really REALLY want a straight up remake with invisible walls preventing you from exploring the entire city? Do you really want a half-assed remake? Play the remaster. It's available NOW on major platforms for less than half the price you'll pay for this.
This isn't for you. Do you really think announcing it early has to do with this decision? This decision is made because its fucking expensive to make a proper Final Fantasy 7 remake. They wanted to remake this since PS3 launch! They just didn't because time and money and employee resource management is a problem. Money doesn't grow on trees, especially when you're complaining about a $60 game. These guys pour their life and soul into it and years of their LIFE into it, only to be told that it's not good enough when they believe that the game will be massive and requires splitting? The game already was on 3 Discs, do you really want them to work on it for 5 years, go bankrupt and release a "Full edition" that people may or may not buy? They're being cautious about it while respecting the game and giving it more time and effort and proper expansion that the universe deserves.
People paid top dollars for Metal Gear Solid V: Ground Zeroes. Now THAT was a glorified demo. People paid top dollars for The Phantom Pain. Now THAT was an incomplete game. It changed the entire structure of Konami for the amount of money they spend (and wasted) on that game.
Let the developers develop. We have a very sour tongue and usually complain about the smallest things. Complaining about how a game is developing is just ranting for no reason at best.
I am cautiously optimistic about this engagement. They have shown GAMEPLAY footage when others blatantly lie in your face and fake it. They're dedicated to this project and all we should do is observe the development and see how it turns up. I'll feel BLESSED if they released the remake in parts of full. I want to play it and I want to explore it and I want to love it and get lost in the universe. There are HUNDREDS of games that release every year. A lot of them are actually very realistically EPISODIC at best. Everything has DLC and more DLC and more ways to scource money from you.
Here you have a developer making multiple titles, some of which were announced last gen and have yet to show. These things, they take time and money. Please be patient and judge the game for yourself (or let others review it). I can name over a dozen games that are going nowhere because the concept is quite complicated no matter how simple they may look.
TL;DR: Time + Money + Effort + Dedicated people giving their lives for your gaming pleasure = be patient and pay when its out and you actually like it. Episodic or not episodic.
