But what was your ideal outcome when you were pursuing sex? If it was really just the possibility of meeting someone to have sex with once, then yeah, the ideal outcome is pretty transitory and the analogy to playing WoW is legit. But if your ideal outcome was long-term partnership and an ongoing sexual relationship, then I think the time spent pursuing sex is best thought of as an investment of time which, even if it hasn't panned out for you yet, has a very big hypothetical payoff (if you are the kind of person who wants an LTR). I don't think that situation is a very good analogy for WoW, where the most you will ever be able to say is that you enjoyed the hours spent playing it, never that they furthered your other goals in any way.
