Good. I'd like to see them work on FF16 and FF7R-2, -3, etc instead of piecemealing it out like FF15.
I couldn't stand how FF15 went. The game itself was alright, but it was clearly EXTREMELY unfinished. It looked like around 80% of the game world had been cut (going off of early concept world maps compared to the actual game's world map). You take a train from one area to another area, and pass by a lot of stuff in-between that looks fleshed-out from a distance, but isn't explorable ingame. There were also a ton of interesting-looking areas on the map that you go nowhere near in the actual game, like a tropical area and a snowy kingdom. At the end of the game you get what is essentially a dark version of the world, but you can't explore much of it and are rushed right to the final area. It's yet another thing that feels like it was supposed to be a major area (like in FFVI where the dark version of the world is like half the game). Even the final area, the city of Insomnia which is so crucial to the game, is significantly scaled-down compared to all of the concept art and what the cutscenes show. Most of it isn't explorable, and you basically run down one street. They DID make more of Insomnia, it just didn't make it into the game. They repurposed the unused area of Insomnia for a DLC at least.
In short, they released a completely scaled-down game, then added DLCs to it over time using unused assets/areas. I wasn't too interested in revisiting the game over and over to play new two-hour chunks; I wanted a finished game. I only played FF15 once, only the main game, and it was the most forgettable game in the series for me. I guess at some point I should revisit it again with all of the DLCs factored in and see if it feels more complete now. Point is, I don't want to see FF16 end up like that. I'm very intrigued by FF16's apparent return to the basics (a medieval setting and crystals, much like FF9) and hope they devote the resources to it that it deserves this time. FF7R-2 I'm less enthused about and expect it to go Full Kingdom Hearts, but maybe it won't.
As for tricks in FF7R, the posts above were solid answers. A lot of it comes down to Tifa and Aerith both being really deep in terms of what their abilities can do. Aerith has an ability that creates a wall to block enemy attacks, and an ability that puts up a double-cast aura. You can use these together to hide behind a barrier and spam a boss with their weakness (very useful against Hell House). 2x -aga spells going off at once is as big of an impact as anything in the game makes.
Tifa on the other hand is just complex, I don't remember it well enough to explain. Giving her the right combinations of materia will make her ATB bar fill up super-fast while spamming certain attacks, and she can dish out massive sustained damage if you're using the right materia and using her abilities in the right order.
For most of the game on Easy you can pretty much get by with just spamming things with magic or physical attacks. The real strategy / high damage output / tricks come into play in Hard mode, where you actually need to know them in order to win boss fights and whatnot. Also, in Hard mode you have access to everything you collected during the game, so if you were thorough in the original playthrough, you can customize your party fully right from the get-go in Hard mode and start trying some new things. It's more difficult to make yourself OP or customize your party to murder in the original non-Hard game when you don't get a lot of the good materia until the second half of the game.
