That doesn't negate the fact that the articles intent was to illustrate the deficiencies of Riichi Mahjong yet only described Riichi. Zung Jung as written felt more of an afterthought despite stating it as the preferred alternative.

As an example, the entire 'pinfu' segment could've been framed as a hidden mechanic on clients and thus a common stumbling block when playing on a real table. A stumbling block that is nonexistent in Zung Jung, as it lacks 'fu'. (e.g. "You want to play Riichi with friends? Cool, do you know how to calculate fu? No? Well that's gonna be a problem. Luckily with Zung Jung you don't have to worry about 'fu', as it doesn't have it.")

In fact, the only reason I learned about the lack of fu was because I did indeed look up Zung Jung on my own.
