Maybe they’re trying to get potential players of Elder Scrolls VI so hyped that they’ll still play the new game even if it’s sold ‘games as a service’ style
The story is really what makes it so good–you start to feel invested in the character, in the world, and that helps with getting deeply immersed in the gameplay. It’s an incredibly well written game.
Beyond that, the screenshots show a lot–it’s a world that feels very lived-in.
Also the gameplay is a ton of fun. Open world, lots of places to explore–some of them beautiful, others treacherous, some both.
I also just can’t really play games that force me to think about my bank account while I’m playing, charging fees or subscription rates just to fully participate in the game, like seeing a bounty hunting mission that requires me to send money before I can start it. Totally breaks the immersion–I play games so I don’t have to think about the real world for a bit. Making me enter bank details wrecks that.
