_This fantasy that a 2D game would allow more content.. really ? If anything it would cost a tone and allow less content, did you follow the KOF evolution ? And what about the sweet idea that FFVI graphics are kinda cheap to produce now. It cost a lot back then.
It wouldn't allow MORE content, but a more of a different type of content that 3D games struggle to include(because of expenses, 3D rendering and size). And I don't think that's a fantasy, but falls under cold, hard logic. Of course, this is not diminishing the effort, saying it's EASIER. No, to create a work of art in 2D is hard regardless, and takes time. Nobody's disputing this. However, it would probably take more time(and a larger team of programmers) to tackle that same artwork, but rendering it in 3D, and in a realistic fashion. Not lets take a town as example. 2D in a similar vein of the old FFs(lets use FFVI, since Uematsu brought it up), the towns are stylized, but still have life to them(rivers flow, water wheels turn, NPCs walk around), now think of it in 3D(but not FFVI-styled, but modern 3D, as in "realism realism REALISM").
Just speaking, and this is personal taste, I'd love a 2D game if it meant they could make a large world with fully explorable towns and the classic shit that, nowadays, developers shudder to think about because it would either put them in the red or they just cannot squeeze that much content in 3D games at all. There are limitations to both(2D and 3D). While nowadays, cinematic-style has gone up, for a change, I wouldn't mind NOT being able to have a game without stylized cut-scenes just to have an older type of experience. Of course, in the dreamer's dream, I'd love a fully 3D RPG world that spans an entire planet, with many towns and quests that rival the larger, older RPGs of yesteryear. That would be amazing. FFXV might
try to do that, but I really don't think something like that will EVER be accomplished unless there is some magical way programmers can come up with making such content cheap and efficient. I'm not holding my breath in my lilfe time.
