Answer:
The demand curve will shift to the right, increasing the market price.
Step-by-step explanation:
When the demand curve shifts to the right, that means that the total demand will increase and the market price of the product or service will also increase at every level. The demand curve shifts to the right when consumers' income rises, the price of substitute goods rises, or the option that applies here, the price of complementary goods or services decrease.
Since the new gaming system is compatible with existing games, the price of complementary goods has actually decreased since you can use existing games that you have already purchased with the new system.
