Most of them do a decent job. Exceptions: Chess - it's a solved problem, and the rest is pattern recognition that won't help. It's still a fun game, but no bet

Most of them do a decent job. Exceptions: Chess - it's a solved problem, and the rest is pattern recognition that won't help. It's still a fun game, but no better than Candy Crush. Strategy MMOs - they'll teach you leadership and training, but mostly taking responsibility. You'll learn to stay up at 3 AM putting your tribe above all else. You'll be pitted mostly against people who thought they could pay to win when things got bad enough.
