MMOs were always my thing. I’m almost glad I don’t know exactly how much time I buried into World of Warcraft back in the day. I haven’t touched it in 15 years and it’s probably still in the lead. I play a fair bit of FFXIV these days but not like I did WoW. Asheron’s Call 2 was a big part of my life for a long time but it’s been offline most of my life.
Among recent games I’ve actively played for years, Rocket League and Minecraft are for sure at the top.
Asia. China and Japan, I know in particular, go nuts for pay-to-win gatcha mechanics.
