I distinctly remember everyone playing Ocarina of Time in 1998. I didn’t know anyone that was playing Pokemon Red/Blue.
You have a really small circle then. Pokemon literally was making the news with how much it was dominating media at the time of it’s western release in 1998.
To be fair, it’s not like OoT wasn’t popular. Even the article says it was second. But Pokemon was a phenomenon
It’s probably something to do with age. In 1998 I was 22. I was probably too old for Pokemon. I remember my nephews played the card game throughout the 90s. I didn’t play Ocarina or Pokemon, but I knew tons of people into Ocarina, like my nephews. Memory is also unreliable and yes, it’s listed as number 2, which surprised me, my poor or selective memory would have placed it number 1.
