Yes, but if you ever buy diamonds, you get a much better deal on PC than those that use mobile. Same deal, same day, same price, more diamonds on PC than mobile.
Blame google / apple who ask for 30% of your revenue instead of the regular 1-2% or smaller that payment providers ask.
They prohibit app makers to use other payment providers then themselves and then make them pay maffia like extorsion fees.
Apple even forbids any mention to any place where you can buy outside the app store, and forces you to use the same price on every platform. (I am amazed that elvenar evaded that rule so far, most likely because there is no mention anywhere of this. except that you can see it of you use both platforms and they never comment on this)
There is a reason there is a huge monopoly lawsuit atm between the giants apple and epic games. (maker of fortnite e.o.)
Not that epic games is holier than the pope, but you need money to battle money.
What effort does apple / google make to ask for billions! (yes some companies pay billions) to them to have the app on the app store / google play.
For example these are the earnings of money certain games that apple / google did not make but extorted this amound of money from.
Honor of Kings ~3 billion payed to apple/google
Monster Strike: ~3 billion payed to apple/google
Puzzle & Dragons ~2.6 billion payed to apple/google
Clash of Clans ~2.3 billion payed to apple/google
Pokemon Go ~2.1 billion payed to apple/google
Candy Crush ~1.9 billion payed to apple/google
PUBG ~1.7 billion payed to apple/google
Welcome to the maffia, thats why apple / google is so much worth on the stock market, there profits are insane, it's like a printing press where you have to put almost no effort in, but get max revenue. and where google has some leviating policies, apple is the worst offender of the 2. google is the local crook, apple is the costra nostra on steroids.
Inno-games refuses to pay that fee, so as an app user you choose, pay that fee yourself, or use the PC.
