Well, there are many aspects of life. Any given game only has a limited scope. For example, most people have family and friends who aren't "competing" with you for every dollar/meal/car/house. This gives you a safe place, respite from the wearying competitive world and hopefully some enjoyment. In regards to the competitive workplace though, yeah, you could say games could be a metaphor in that regard. Again though, workplaces are varied and larger in scope. People can also jump between workplaces to their benefit - which AFAIK doesn't work with games.
