"Losing is fun..."
With respect to "Losing is fun" in general:
In fact, no - for many people it's not just the resulting improvement that comes from it, the actual process of losing can be fun. This is something that can be born from the imagination and immersion. The circumstances surrounding a death can be hilarious, the "quest" could have be epic, but not all quests result in glory. The stories you may be telling yourself in your head while you play and the uncertain outcomes can lead to excitement, sadness, frustration, relief, joy, ...etc. So for many folks indeed losing can be fun. This is a concept I first encountered playing pen & paper rpgs.
