Around my region, South America, everybody used MSN as well. We went through a phase of using Skype, but it was too resource heavy in comparison with MSN. Later on, people who needed voice chat for games played around with several different apps, until we finally settled with Discord back in 2016. Say all you want about Discord, but I’ve been using it for almost a decade at this point, and if your need is to have voice and text chat and easy screen sharing for gaming, it’s basically the golden standard. The problem started when people started using it as a replacement for forums.
