Edit: There are so many answers that I might only reply if I have something interesting to say. I will read all of your answers though. ๐
Edit 2: It has become too much for me and I have to disable notifications. Thank you for the massive response and please continue to discuss with everyone here. โค๏ธ ๐ซก
AuDHD means every game is part of an addiction phase. I will binge a game for like 100hrs then drop it out of nowhere. Then return right where I left off anywhere between 6 months and 4 years later.
