According to the video, the economy in Path of Exile 2 is designed to be player-driven. This means that the value of items and currency is determined by what players are willing to trade for them. There will be a gold currency that can be used for instant purchases, but players can also choose to trade items directly with each other.
The developers are aware that this can lead to situations where it is more efficient to trade with other players than to use the in-game systems. They are planning to address this by making sure that the gold price is set at a reasonable level and that trading for currency is cheap and easy.
One of the challenges of designing an economy for a game like Path of Exile 2 is that there is no real-world equivalent for many of the items and currency that exist in the game. This makes it difficult to determine what the true value of something should be. The developers are planning to address this by fine-tuning the economy based on player feedback during the beta test.
Here are some specific details about the economy in Path of Exile 2:
It is important to note that the economy is still being designed and these plans may change before the game is released.
