I don’t know how anyone has time for two live service games at once

Think of an MMO as a theme park. Used to have to wait in a really long ass line to get to each of the rides. Now, you have fast passes to get through all of the attractions as quickly as possible. This explains the MMO market nowadays. If you subscribe for 12 consecutive months to World of Warcraft, you won’t have enough stuff to play. The gameplay loop when you get to end game is essentially brainless and monotonous, it requires no time investment really at all. You just log in daily to do some repeatable tasks, Then you spam the exact same brain dead content over and over again currently it’s raids or dungeons. They added a scaling system about halfway through World of warcraft’s lifespan. So you either go normal heroic mythic raids or you do normal heroic mythic dungeons and then mythic dungeons scale all the way up to like the 30s so you just repeatedly run the same exact stuff over and over. Lots of people don’t have the fortitude to do this, so there is a lot less time invested nowadays in a single MMO and a lot more interspersion across other MMOs.

Elder scrolls online has some pretty good story content, but it’s not enough to keep you busy for an entire month either. Some people swear that it’s worth paying for and subscribing to the game for. If you don’t subscribe to the game, you don’t have any crafting bag, and by extension, you don’t have any inventory space to hold any materials, so it’s almost required to subscribe to Elder scrolls online. You can buy all the expansions with money, but that won’t give you a crafting bag and a bunch of other goodies. Game becomes virtually unplayable at that point and it’s frustrating
