Creating games in the future

This story was written in my language and translated into English using Deepl.

Alexander Lockhart is reborn thousands of years in the future, and discovers that the earth he knew was destroyed a long time ago, all of humanity became militarized after the start of a war with the alien race Exceed, fortunately he was reborn 200 years after the end of the great war, while exploring this world, he discovers the precarious condition that the entertainment industry is in, perhaps this is his chance to make his dreams come true.

This story will have a slow start, the protagonist will begin by doing small things, and only when he is older will he go into the games industry.

There will be no harem and no lemons.

Have you ever had the feeling of showing a friend a game or movie you really like, and then they start to like it as much as you do? That's the feeling I'm going to try to convey with this story, and I hope I succeed.
