As others have written the stars are a bit much. Trying to save up for the last two is a bit insane. Also the prices don't match well for the number of stars required. Right now I only have 31 stars saved with the next business requiring 67. The purchase price of the next business is only $1.15 quadrillion yet the Electric Corporation alone is earning me $5.441 quadrillion per second. It would feel better if the business required several Quintilian dollars to buy, and just started at a higher payout. Finally this game does not run in the background at all that means even using another tab in the internet browser I gain nothing (it does work in a separate window), Idle games should make it easy for you to do other things while "playing."
