Imo, the releases of their smaller games were totally mismanaged. There is nothing wrong with making games like Diofield, Harvestella, and more. Neither is making remakes. pricing was also a biyt off. These kinds of games should be released in between big releases, like for example, you release FFXVI, and then the schedule is empty for some months. In this case, let us assume that FFXVI turns out good. THAT is the time to capitalize on momentum and release smaller games, until your next big thing is coming up, in my example case FFVIIR2. Release more smaller games, and so on.
They just released, low budget game after low budget game. Star Ocean 6 was made on a shoestring budget. Romancing SaGa Remaster (a game I love) is a niche game, Diofield is decent, harvestella is supposed to be good. Stranger of Paradise is certainly a game that could have benefited to release before XVI, and maybe have a demo included. There are many things that could have been done, but to rely solely on "smaller" games released in such a short time span isn't really feasible, which they learned the hard way.
