What you say makes little sense. Also, you yourself only released 2d games, so answer the question yourself, why games are 2d and not 3d.
Also, there are games with 3d here.
It was my 1 public game and last , But it was a lot more easier than 3d one , in case you are making from scratch. In addition I can say it skill based work and needs understanding of concepts.
But idk why I didn’t look back 🤷♂️😄.
