In my opinion, it’s better to focus on hero-related trivia rather than general knowledge, excluding, of course, questions like naming 104 elements from the periodic table or all European countries.
And whether to include or not include – that’s exactly what the question is.
And one more thing. Regarding Brain Ring and any similar format. Coming up with one interesting question takes time. Some questions took up to half an hour just to verify. And even then, there were disagreements. But I can confidently say that the final questions were the most interesting, and as a host, I was most interested in the final.
But truly interesting questions about Heroes – no matter what anyone says – are limited in number. Questions like “how much HP does a simple centaur have” are unnecessary and boring in this format.
