Improved Store Front
Steam has been a pioneer when it comes to individual store pages. They offer a community hub where people can discuss the game they purchased, there is a way for users to give review scores to games they have played, and there is even a news section that provides updates from the game developers for patches and other useful information.
Unfortunately, the Epic Games Store does not have any sort of functionality that is similar to what Steam currently offers. The store pages on the EGS are pretty bare-bones, and only offer a way to purchase or pre-purchase the game, as well as a few photos and system requirements.
Another frustrating aspect of the storefront is the lack of a shopping cart. In order to purchase multiple games at once, you have to buy them one at a time. Unlike Steam where you are able to add in as many games as you want into your cart, then purchase them all at once.
This is especially frustrating during sales, as you may want to buy multiple games at a discounted price without the hassle of going back and forth to purchase them.
Adding something as simple as a shopping cart, something synonymous with online shopping, is just one of the many ways that the Epic Games Store can improve.
