If the price of Among Us 2 goes up compared to Among Us then the quantity demanded will go down but the demand for the game (and the supply) will stay the same. This means people will still want the game but less people will buy it overall. That's considering the demand for Among Us and Among Us 2 will be equal but personally I am excited for Among Us 2 and the new content it will bring. Very smart of you to bring supply and demand into this though. You should be an economist!
