Without the neon sign, you'll need around 200 billion shares to max out everything. For the level-101-sign it's almost 10 quadrillion shares!
(if I calculated everything right and - like you said - if the wikia is correct)
So... it's as insane as it is useless to max out the sign. Its share-multiplier only helps when you're always selling your company after a short period of time. But since you're bound to use the stock market to reach the higher decoration-levels and to give up the futile sell-sell-sell-strategy most players seem to use... well, you probably see why there's no real benefit in this. When everything is at level 101, you just don't need the shares anymore. As long as they aren't adding more decorations.
And buying/selling stocks for ~1 month longer (assuming you're going up ~1200 levels per day), when you're already at 200B shares... okay, *I* am going to do this. But it is meaningless nevertheless. If you can live with the nagging feeling of imperfection and a prestige bonus slighty below the maximum.
PewDiePie pack? Wow, that is stupid. They even made up a bogus "original" price of 10K Nutaku coins so it looks like you're saving money.
Sadly looks like they're turning the game into a cash grab with content locked behind pay walls.
2K Nutaku Gold = $20... as if they were going to ever sell it for 10K($100)...
Do they think we're idiots or something? Who in their right mind would spend a $100 for a crappy skin, 500 Rubies(which you'd have to pay $40 to get normally, which is even more ridiculous), and an animation that you might fap to once.
$20 is still way to much... I'd pay like $5 for something like that...
So what is the point on playing this if they are going to straight up sell content? And for 20 bucks no less, what? Also for Amber, and animated. Come on fuckers I have been waiting for that "Coming soon" or whatever it said since you put up the game.
Also, can anyone tell me whats that about getting shares with the stock market? I thought it was just to get money.
Well... yes. Of course the stock market is for getting money. But with this money you level up your girls. And the number of those level ups determine, how many shares you get when you sell your company.
So: more money => more shares
But this should only interest you if you're obsessively trying to reach questionable goals like being in the top 10 of the weekly 'tournament', maxing out every decoration, etc.
To see all (free) content of the game you don't need to use the stock market at all. Or use any other kind of pseudo-strategy.
How the hell do people have 56k+ levels already when the weekly tournament started 6 minutes ago from this posting?
