What is the best way to build a AI with human-like skills ?

I'm making a Real Time Tactical game with focus in AI, theare are many cases applying Reinforcement Learning and Genetic Algorithms but in more simples games like Snake and Asteroid, I see some work from DeepMind in Starcraft II but with more computer power, far away what a Indie Dev has. In this case will be better a hard coded rules system than Machine Learning ?
