I'm hoping Star Ocean 6 will be a huge hit. I have had mine on pre-order since pre-orders went live. However, with Persona 5 still being very popular and releasing the week on all platforms and Gamepass the week before and Modern Warfare 2 releasing the day afterward, things are not looking up, IMO. I will try and split my time between Persona 5 and this game, but I'm not sure how many people will do the same.
In the future, they might have to abandon engine development, at least for a bit. It might help Tri-Ace get to a point where they can afford to make big-budget games again. Getting used to making games using industry-standard engines will also allow them to take up more work supporting other studios if necessary. I know it's not a popular opinion, but there is a reason many AAA studios are at least doing their next current-gen game on UE5 if they haven't abandoned engine development altogether.
On the technical and gameplay side, Tri-Ace has the talent to be a valuable asset to one of the console manufacturers if it were possible to purchase them, IMO.
