This medley really shows how much better the choreography has gotten over the years. Ignore the solos and just look at the first and last songs. In Tulip, it's five girls lined up on stage, they perform the same animation file copy and pasted across all the models, and they don't *move*, it's like they're a rooted character in an MMO. Sure, the animation might move then forward or whatever but it feels like they're still actually in the same spot. Compare that to Nightware. It's still five girls on stage, but they actually like, move around, different girls will step up to center, they have moves that take advantage of the fact this girl is left of center, this girl is right of center, etc. even the bits where they're just doing the same moves, each has slightly different timings, making it feel more real.
