I cannot recommend this game to anyone.
It used to be worth playing - but isn't anymore. Devs are making it worse with every single update within the past years: research progress takes years (literally), economy is messed up and only getting worse, they are introducing new broken mechanics and bugs instead of fixing current problems.
Every single update brings new overpowered premiums that cost up to 70$ which only serve as a shortcut for new players to skip the unbearable grind. The worst part about this is the fact that progression was intentionally designed this way by the devs to incentivise players to spend a whole lot of money to progress faster.
And this issue has only been getting more extreme as of late, with planned changes by the devs to further worsen the game's economy and progression.
