No, they’re not even remotely the same. The retailer keeps 30% of the retail price and, out of that, they pay for the upkeep of the store. It’s not 30% pure profit, it’s not even gross profit given they need to pay the card processing fees out of that 30%.
I’m not following how that is a response to what I said. I’m not talking about Valve’s profits. I’m talking about the profit of the game developers selling their games on Steam.
I think I understand why Microsoft costs are higher than others due to their a spending spree, so the break even is much higher.
