@05841035411 already gave one version but i'd like to extend that a bit:
- How many idols do you get at the start?
This heavily depends on your overall strategy. No more than 3 idols will actually do as well as any number above that. This is mainly a business simulation which means every additional idol in the beginning also means extra costs that could be used in other ways. All fame etc is based on 'center' of a formation. So even in a backline someone more centered gets more fame than the sides. This goes on and things get more complex the more idols you have.
IMHO one of the most important parts of a good strategy combines 2 things:
financially stable and
ability to gain fans.
This is why i personally would answer your question with: go for only
3 idols but be picky about them. Why only 3? Because the steps to level up
promotion and
performance only require 3 idols. One of your early goals should be to open up
promotion as quickly as possible as that enables you to earn proper money with releases. Ignore
performances for a bit as it usually opens up naturally when you follow a
promotion strategy.
Local auditions cost only 100k but you have a chance to get silver idols for each of those 5. It is chance based according to your influence which levels by going to auditions
- you see where this is going, right?
- What quality are those idols?
With your characters 'influence' the ability to get higher level idols on lower level auditions raises. At the start you wont have any but you already have the ability to 'get lucky' and get 'silver' idols in a local audition. Higher level idols simply means they both start with higher base stats and usually also have higher 'potential'. Here it is important to have a clear strategy for your releases ready. One step of the performance level ups is to reach level 5 for one genre - so you want to stick to one genre for quite some time to level up naturally in it.
So the main point here is not what level the idols are but to think about your facilities and the idols stats.
Example: I decide to cater mainly to hardcore fans that are male and mostly adult (hardcore because they will by more than 1 copy later on etc).
So i combine this way:
Knowing that i only need to hire a dance instructor to open up the 'policies' tab i look for idols with high stats in vocal and high potential in sexy. This means i dont need to train any of them in singing but can enhance their looks and dancing.
Why exactly those? The first level of the building is completely rent free. Pointing back to the first question: financially stable. You need facilities to make your group better but you dont want to overextend too early.
The first level allows me to place my own office, one office worker, 1 make-up artist and a dance studio without costing any ongoing rent. That gets you a long way if you think and hire strategically.
My example is only an example - if you want a different audience simply choose idols with the proper stats that cater to those.
- How often do you release a single?
Max 1 per month. Releasing more not only hurts your income but also lowers the trend for that specific genre which reduces sales figures even more.
- How do you manage to release singles on an often enough basis to get money while keeping stamina high to allow for concerts? (I haven't been able to do a single concert because I've never had the money, much less the stamina).
In the beginning you cant queue actions which means you have to keep an eye on everything. To have a 'good' start you want to have as many fans as possible for each and every release to make a profit as quick as possible. Dont let your office worker look for business proposals but just let them research until you have opened up 'digital release', 'photoshoot', 'advertisement'.
Keep doing promotions and everytime you get a 'restore 10points' spa ability use it. All other actions continue to be promotions. Your overall main goal is to reach level 4 promotions as fast as possible as that yields a decent number of fans per promotion.
- Do you do the once-per-day events that boost fans, stamina or money? If so, how often and is there a pattern that you use (ie: for every 2x fans or money do 1x spa)?
See above
- Do you do photoshoots or any other side-gigs? If so, how do you manage that stamina loss?
Only after the first concert. After the first concert i usually immediately invest in both a doctor and a rest room. Those 2 combined with the strategy of the promotion and spa combo i described above means, you will usually never have any idols totally exhausted if you assign photoshoots and ad jobs properly according to idols energy levels.
