Conventions and gamer tournaments have developed a good reason for having a funky reputation. Card games are no stranger to this nasal phenomenon, and apparently the prevalence of odour is so strong at Yu-Gi-Oh tournaments that Konami has now officially introduced a rule penalising players for their hygiene.
The official tournament rules were updated on Thursday, adding a subsection specifically around hygiene. It's short and sweet, and says the thing that nobody wants to say but everybody has thought at least once when attending a con or a major card game tournament: please shower.
A large part of the problem with game stores is a lack of good ventilation, rather than the players. Without good airflow, one bad curry fart can decimate the whole crowd. But the level of human bioterrorism at Yu-Gi-Oh tournaments is obviously next level.
Part of me shudders that this even has to be officially sanctioned. But just imagine being the poor judges who have to enforce this.
