Has anyone figured out how glowsticks work exactly? What's the difference with the top one Ultra Orange that's so cheap? What do I get by having them activated? They aren't running out at least it seems. Just what do they do? Yes I registered just to ask this but I'll try to join the community as well!
The glowsticks are something from the real live im@s concerts. In general there are 2 types of glowsticks: battery powered ones, and chemical ones. Battery powered glowsticks are self explanatory. Chemical glowsticks are activated by "breaking" them, this causes a glass tube inside to brake and 2 chemicals begin to mix, mixing them causes a reaction that emits light. Chemical glowsticks, and especially the ones called ultra orange, or UO in short, are very bright, but quickly get dimmer. Let me put it like this: at the 10th anniversary concert, you could easily spot someone on the other side of the baseball stadium who activated a new UO halfway through a song, even though everyone in the stadium was waving at least 2 penlights (or UOs activated at the beginning of the song). UOs are typically used for what i call "hype songs" (such as Ready!!, Jibun Rest@rt or The Idolm@ster), or if a song holds special meaning to you or you like it especially. I used over 50 UOs at 10th (2 days for 5 hours each), even though i also had battery powered penlights, and a lot of people used much more than that.
Of course, UOs are much cheaper (about 80 yen a piece iirc) than battery powered penlights (the set with 12 765pro penlights was 15'000 yen at 10th iirc).
So in short: i'm pretty sure that in the game Ultra Oranges are brighter and cheaper than the other penlights, but can only be used once (hence you can buy multiples of them). I got the game today, but i couldn't play it yet (Vita battery is dead and i don't have the charger with me).
But what the glowsticks in Must Songs do in general: the audience will weave them around, just like they do in real concerts. From videos before the release i think you have to activate them in the beginning (or during) a song in Must Songs.
