Speak for yourself. I though Episode Duscae was a pretty well done environment to explore, for awhile, or at least showed potential. It wasn't that the area was wholly uninteresting that was the problem, it's that 1) we could only run to places and 2) we were stuck in that small area. Combine those and yeah, it ends up being an experience that doesn't offer endless amounts of fun & excitement to just run around in. I imagine chocobo drifting alone will make exploration So. Much. FUN., much like Nier's boar drifting is one of the GOAT modes of travel. Not to even mention that close by the ED area is that flaming crystal thing which would obviously be something that gamers will be drawn to and will be interesting to get closer to.
And FFXV will absolutely have long stretches of "nothing" (we already see this in the coastal video, it doesn't look like there is a treasure chest to be opened or a super boss to be fought every 5 meters), so better just be prepared for that kind of experience, though nothing doesn't have to be NOTHING. It can be a regular forest where you can battle some enemies and randomly run into a wild behemoth that might offer an intense battle, or find a lake you can fish in. Not every square-inch of the world needs to be packed with some super unique content handcrafted just for that location, let alone content like the boring-as-hell question marks in The Witcher 3 that are a complete waste of time even when you know you aren't exploring the area for nothing. There's nothing wrong with long stretches of this "nothingness", so long as they use good environmental design to point out & lead the gamer to the more interesting locations, so that gamers don't feel like they have no idea where some points of interest in the map might be.
