I don't doubt it could, but that is besides the point.According to Steam Spy it's under a mil. Sure it seems like it was a cheap port and it likely didn't take much to break even, but you aren't being honest with me if you don't think it could sell far better on PC
We don't know how much SE needed it to sell for the whole FF7 Remake revenue on every platform (added with Sony's money and exclusivity deal) to make sense and turn out something they hoped it would.
Like obviously every game sells better as a day 1 release, but the released game, its quality and all the revenue gained from it is what matters, not hypothetical revenue streams for situations that maybe aren't even realistic possibilities (i.e. Remake releasing as the exact same game day 1 on PC and at the same time it originally came out on PS5).
