The fun, of course, is when something interesting happens. It's not the destination that matters; it's the journey. For instance, during the last round at the Pasadena Regionals, I was ahead of my opponent who was using Gardevoir Lv. X (you know, the one with Bring Down). Then, Dialga G Lv. X happened and it, by itself, turned the match around and gave him the win. Turns out that, after the match, he had expected to lose as I had the lead during the first two thirds of the match. I loved that match because it was interesting, it was unpredictable, and we were discussing it after the end.
I might have lost, but I preferred it over the turn-one donks I was doing with Raticate in the Long Beach Regionals the following year.
Really, you could drop out of a tournament at any time. I see a lot of people drop out starting in the middle because they have too many losses that they can't make the top cut. If everyone cared only about winning, or if the environment encouraged something like that, you'd have people dropping out in huge numbers with hardly anyone left by the last round or two before top cut. That I still see hundreds of people at the end of a tournament, still playing even though they know they won't make the top cut, makes me feel good because it shows that there are noncompetitive people who attend them. (Definitely not coincidentially, the atmosphere gets more mellow from the midpoint onwards.)
