Steam also did the legwork to adapt to other countries' cultures, means and payment systems.

They do regional pricing, including systems which make it difficult to pretend you live in a poor country, which you absolutely need if you want publishers to adopt that. They do local payment methods. They let kids (and kids and teenagers are an important part of this market) buy gift cards in physical stores, and pay for them with cash.

Mobile App Stores are a lot worse at all of these, especially Apple's.
