I want to make the effort to understand your perspective here OP, but for some reason I just get the impression you don’t understand this game very well.
Cubits are thrown at you. You get cubits for damn near anything. Every time you level up after level 50, you get cubits. It never decreases, it just keeps going. For those of us that run fixed builds, you end up piling up 7 or 8 thousand cubits very quickly. The only time I use them is to change from one planetary resistance to another.
Coins are used for player to player interactions and some very minor ingame cash sinks (transit). The chrysominter vomits coins are you with such regularity that you can have a scrooge-mcduck style vault of coins if you so chose.
So what, on earth, are you talking about? That people can swipe a credit card and get a few thousand plots vs. grinding and getting a few thousand plots? That is literally the only difference. Nothing else.
There is no reward for buying plots. You have to do something with them. Effort is involved. There is no core reward with just plotting up half a planet. You need to invest energy, materials and creative ability. Then you might get something out of it, which may only be your own satisfaction.
I saw this nonsense on the steam reviews: people with 1.5 hours of played time going “ITS PAY 2 WIN”. The player takes zero responsibility to understand the game and make no effort to comprehend that they can actually earn everything. They want it all, right now, and what no one else to have more than them. That level of entitlement is hilarious.
As a criticism, the developers could certainly do away with the chest animation. Its cheesy and gives a bad impression of a reward. If you are going to have quests, the sanctum guardian guy should be the “quest giver” and not “loot boxes” or whatever else is the perception.
I said in another thread that when these concerns come up, they are either a gross misunderstanding of the game mechanics at best, or intentional deception at worst. It applies here.
