Hello Metzli,
Any Ego from Missions is permanent and this value will only go up over time.
If I get a lot of Drunken Fans from missions, this can increase my Ego.
But Drunken Fans forget about you after 12 hours so my Ego would the diminish again.
Having a high Luck value helps to get more Skill from Music Lessons, but it also increases the chances and quantities of Drunk Fans.
I like to have a higher Skill to combat these random increases of Drunken Fans to reduce the chance that my Ego kicks in.
So by buying lots of luck you get lots of free temporary Fans to increase your Starbits earnings potential and having a larger buffer of Skill means you don't lose Starbits earnings potential.
I hope this helps to answer your question.
This kind of answers my questions.
I see that the ego meter can only get to 100, does this mean that eventually, because of the missions I do, my meter will get to 100 no matter what?
Its confusing because I see some people with really high levels and zero ego and I feel like I will never be able to do that because I already have an ego that is in the 20's even though my skill is higher than my fans.
Or does this mean that I have to stop doing missions throughout the day so taht my ego never gets high?
