It's never late. You can start again in the field of Game Development. The fact is, low quality AI content is heavily criticised in the field of Game Development.
If you can make the best in the military game genre, that is a unique element of your game. Like my unique element is psychological horror, you also have one.
About the views, Even my games don't get views for straight 6 months when I first started. If you want your games to be played by people's, join game jams. People's directly play your game and rate them. Try it out, that will regain your confidence.
Also your start is very similar to how I started game development. You can read the story in my profile C-mastered studio. While I also downloaded a 48 hours C++ programming tutorial like crazy.
A little advice: Game development is an art of programming and imagination. Enjoy it!
