Since the massive increase in cost, it feels like the upgrades simply aren't worth the immense amount of wealth you need to make to even buy them. Dependencies I could deal with, making progress effectively 0 does not.
Not really encouraging to return to a game if it takes 20+ days of no input to reach the next upgrade.
No, that was not the intention. I think something is wrong in the calc of unused prestige when they was bought at a diferent price. I'm on it...
