[Tactics]

Apple and orange can't even think of looking feedback from each other on how to make themselves tastier.
Both fruits also didn't involved in talk with Toriyama, Kitase and Nomura about "How to do DLC for Final Fantasy" as development cost for long run matters.

VII Remake already proven the staffs learned from XV to respect limit to made things possible while Intergrade did well on telling this is how FF VII R will do additional content. Surely you won't say XVI staffs better not learn something from their workmates;

Good if you have better solution on how to do the games without learning something from them, because I'm pretty sure Yoshida understand decision behind Tabata way of handling development cost by planning lores and other weapons specific gameplay behind DLC as it similar to how XIV did some part on its storytelling.

Honestly there's no harm on doing main game focused on Clive and his party while DLC expand Hugo and others while offering other classes to play assuming they're not playable. Both Yoshida staffs and DMC staff have the experience, the only concern is how to strike balance between value and price unless they decided either No DLC or going with Special Edition / Intergrade.
