I tweeted some impressions from my time with the demo. Needless to say, I really really enjoyed it.
Combat felt great. I love the use of stopping time. I love how often I swapped characters and used ATB charges. The thought process of managing just those mechanics alone were super exciting.
I was super worried about gameplay since it would obviously not be traditional ATB turn based combat. But this really captures the spirit so well. Very, very impressed.
I have some more thoughts in this Twitter thread if you wanna read
Your impressions (and seemingly everyone that goes hands on with this so far sharing the sentiment) and comparing it to the MGS2 Sons of Liberty demo in terms of impact is making me very hyped. I would love for Square Enix to release the demo to the public. Feels like Final Fantasy X was the last time the franchise was a juggernaut event and a technical showcase. FF7 Remake is a big return to form in that regards.
