Reflections On Game Genres

What I learned from the games I played was math, science, and etc.
Those games also gave me ideas of how I can design my game.
The games that stood out to me the most was the sports games.
I thought those games were really exciting and I also thought they can be improved.
Some questions that I had from play those games was...

How do you get the animations so detailed? I would like to make something that good!
