I thought this would be as good of a day as any other to write something about the RisingStar game.
The game has two very important qualities, in my opinion:
I probably don't play it optimally. But I set a strategy and stick with it, with minimal updates for a while.
Until not so long ago, I did the following:
Currently, I have enough STARPRO for the 10% bonus, but I continue to play Music Promoter every other day (maybe I'll change that to a rarer pace), while on the days when I don't I withdraw the STARBITS from the regular missions along with those from RS Millionnaire to buy packs quicker.
I also started playing the Promote Fan Club missions again since I had the extra STARPRO.
Since I used part of my STARBITS to get STARPRO instead of buying packs I started to drift in the ranking a bit. I also don't always remember to launch a mission, which obviously hurts my ranking. But with plenty of things to do, I often only check the game in-between other tasks.
If what I've shared helps you in any way, I'm glad. If you have something you'd like to share about your strategy, what works or doesn't work for you, please do!
