By the way, it does remind me:
Do you think it's reasonable to set "release a single" as a requirement of level 2 promote?
Release a single means you need to have a dance room and recording studio at least.
But you will mostly go bankrupt if you did it in the early game.
It's paradoxical.
You need to promote the performance and promotion for better efficiency of accumulated capital. Ok, You need to release a single first. For that, You need to buy a dance room and recording studio. But you don't have enough money. So you need to promote the performance and promotion for better efficiency of accumulated capital. See?
