While they didn't take it too seriously in the quick look, it's what push me over the edge for my purchase and I'm pretty happy I did. I think the music is great and the rhythm game is probably the best I've played in quite awhile. God tier tune is probably one of my favorites as well. It's good for diva point grinding as well since I clear 66k diva points each time I play it on hard.
While other parts of the game like raising my affinity with the vocaloids is strange but not entirely boring.
I really hope Sega brings the next game to the west. While I know I could probably have troubles importing it, I prefer not to if I don't have to.
