Played through the demo three times yesterday.
The presentation of this game is magnificent. I don't think anyone doubted Square in this department, but they delivered, they captured the essence of FF7 from the atmosphere to the look and feel of the world.
The music arrangements are nice, I don't know if I'd say I like them more than the original... I have to give them a proper listen through headphones and not my television set, but as long as I was able to instantly recognize everything, that's good in my book.
Biggs, Wedge, and Jess (especially Jessie) have a lot more character now. I never really got attached to either of them playing through the game as a kid, but it seems that they're going to get built up this time around.
The combat. This is going to be the biggest point of contention in this remake (outside of splitting up the game). It took me a 2nd playthrough to truly grasp the combat system. In the first go, I didn't care for it. I thought it felt clunky and that things didn't synergize well. I was constantly hitting the wrong buttons, bringing up the wrong menu for the wrong character, hitting ability instead of spell, or spell instead of item. Ugh, I hated it. On the 2nd and 3rd playthrough? It clicked and everything was smooth like butter. I was issuing commands, swapping characters, hitting abilities with no problem at all.
I'll reiterate some of the same statements others have made about the ATB gauge. I understand it throws in strategy and tact to decide when and how we should utilize those ATB gauges. However, I still think it's rough that magic costs MP and requires an ATB gauge as well. Items being tied to it with the possibility of being canceled by an enemy attack/knockdown, the game definitely punishes you from not recognizing attack patterns. I also think this is a game where a lot of players are going to want to spam potions/cures, lol. Lastly, I feel like the ATB gauge is prime for expanding slots, sorta like in FFXIII. So by the end of the game (maybe not part 1), you'd have 4-6 ATB slots on a character (thinking something like, say, Knights of the Round, would cost 6 ATB points).
Square has never been my favorite developer when it comes to ARPG's. I know people love and defend KH combat systems, but I've never fallen in love with them. FF7R lands higher than FFXV for me (which I thought was abysmal), it's not the perfect system I'm looking for (I have some issues with the Guard Scorpion fight), but it's serviceable and will get the job done. Hopefully without me ever wishing that I was still playing the turn-based version of the original.
