It could be a small surge but something where you noticed a sudden influx of people. Maybe a game you were playing that got quite popular after it was streamed or there was free weekend on Steam.
For example during the quarantine and around the time when the used console market got prohibitively expensive handheld emulators like the RG350 and much later the Miyoo Mini got quite popular. This was partially due to more people at home wanting to play their favorite classics but also them being promoted as “fake” GameBoys and PSPs on TikTok.
A group of professional voice actors streaming it on Youtube.
What would it be in this situation?
D&D. I genuinely thought Critical Role was so well-known that everyone would know what I meant.
Your problem was in how you described them. While you are correct in that they are professional - they are a bunch of “nerdy-ass voice actors.”
However, I did originally know who you referred to.
