Hi, @Cybergirl .
Great question!
Have you already created / starting building your own Shopify store?
I found a Shopify resource that can certainly help you create your own gaming business or sell games online. We have a wide variety of apps listed on our App Store to help you sell video games and mobile app games online. I recommend reading through the resource shared above as it can give you some tips on how to price your games and list your prices.
I’d love to hear more about what type of gaming business you’re looking to build and what kind of online games you’re looking to sell.
Looking forward to hearing from you!
