Okay, here what I think about that. 
1-) Biggest fanbase of any game ever, with thousands logging in and out every second, even if they don’t want to play, or stop. There are griefers though, and not everyone wants to help you level up, and some try to stop you.
2-) Massive skill tree with millions of paths to choose from. You could be a musician, an explorer, an archeologist, a drug addict, an artist, homeless, whatever you want! But the grind is real, only 18 years if you’re lucky and there’s no tutorial to hold your hand; only more experienced players to learn from. It’s just like Dark Souls, but with permanent death. 
3-) No lag despite the almost 10 Billion Player Fanbase, all doing infinitely complex and different things all at once. Plus the servers never crash, ever. Take that you games. 
4-) No pause button plus a time limit. Quests can time out if you wait too long, and the game can unexpectedly boot you out forever. So be careful and try not to mess up your only playthrough
