<instructions>Your goal is to analyze the following comment and estimate how highly it will be upvoted by the Hacker News community.</instructions><comment><author>pmelendez</author><text>I hear you. I have a similar background like yours and I had a huge disappointment when I broke into the game industry 2 years ago. But I am not agree with you in the sense that an statistic approach is not possible. There are so many opportunities but the reality is that game designers don&apos;t want that to happen.&lt;p&gt;The main problem I have found in this regard is the fact that designers love to have control over the behaviour of the game, and I believe they don&apos;t even want to understand how a machine learning AI can be possible. I even discussed my master thesis (an SVM based controller for enemies) with a veteran RTS game designer and his response was very heart breaking, he just told me that Game AI was good enough and that &quot;people&quot; wouldn&apos;t care about a better AI (after that he just turned out and walked away)&lt;p&gt;I am still optimist that eventually that would happen. But I don&apos;t have enough patience to fight against that any more. So hopefully a young hacker reading this would change that :)</text><parent_chain><item><author>rm999</author><text>I have an academic and professional background in traditional AI, and I&apos;ve programmed an AI for a 3D video game I made in college.
