Hello,
In the past, for educational purposes, gamers made just small games like with Python code or a game with a small portion of C# or these static files that you input data and get some entries.
Indeed, programming with Python or C# is not deprecated. Still, nowadays it is no longer suitable for a gamer to play on a website made with Django and React Js rather than downloading a mobile application or its web version and playing there.
Because to make a 3D game makes a lot of features similar to real-life, especially for all games mobile developers either for Android or IOS or dark code or especially Flutter by Google which could render Android and IOS to make a mobile application for Google and Playstore.
As with any competition like product competition like the marks providing the food or the elements to clean the house or books, E3 could let many gaming companies meat and in this meeting, they could find the points of the force of other gaming providers and then decide if they will continue developing this feature or discontinue based on what other gaming companies are programming and discussing their feature plans to enter to metaverse and web3.
