The game framework is simply one of many tools we can use to engage life with less fear. People who are very fearful in their approach to life may find it easier to be fearless in a game world. People who are financially broke may find it easier to accumulate wealth with game gold. I also know people who've turned game relationships in MMORPGs into real-world relationships.
The analogy has its limits of course, but personally I find it helpful for keeping things in perspective, such that I feel empowered to take action rather than overwhelmed by circumstances.
