Is there a chance it's not just "about the feels" but also about team building that may pay dividends later when it comes to "normal work"?

I'm not saying the method used was effective in that regard, but it's possible the aim went beyond what was immediately in front of you. Strongly bonded teams (whether built socially or through adversity) tend to be better teams.

I know HN probably skews towards an industrious/utilitarian/pragmatist point of view, but many of us probably work in teams where not everyone holds the same perspective. Understanding how those people work and are motivated is important.
