I want to start making something similar, I have some ideas. I have already started doing research and tutorials with the platform I am comfortable with and have started learning about Unity and other engines.
My question is that, does a game like that requiere a lot of people to do the graphics/animations. What is the size of the team who made these two games?
In his explanation, he states : "The math engine is in C (JNI)"
I was just wondering why would this user want to use a math engine written in C through JNI and not just implement it in Java. Also, can someone help me better understand when you would want to use JNI and how it really works?
