I'm not importing - just looking at online videos - but I think this game shows a lot of rethinking about underused features in previous games. Diva room, edit mode, and accessories come to mind as features that a lot of players probably didn't bother with or could not get deeply into. So the first two get scaled down, and accessories gain a gameplay function.
What I don't know is whether this also reflects a long-term trend about making PVs more economically in terms of both money and time. I mean, in the two years between F and F 2nd Sega was able to make 20 full-fledged PVs for F 2nd - and some of these were visually gorgeous and not matched by anything in X. But that's still not enough for a full game without recycling other stages.
With the current style I think they can at least consistently achieve the level of something like Satisfaction or Lost Ones, with lots of visual detail and camerawork. But Renai Saiban is just barren and underwhelming for one of the most popular songs in this game.
But wherever things go from here, I'll always have Two Breaths Walking and 2D Dream Fever as the visual pinnacles of this series. And the old edit modes to play with.
(At least Lost Ones acknowledges that it
should have been a guitar song...
)
