I mean, I don't care about either of those games and am not excited about it at all. As is the case for probably many people on an enthusiast board like this, they arent really my cup of tea and I would ahve gladly taken Generic Shooter 15 or Fantasy RPG 8 over these titles.
That being said, my girlfriend will be super pumped; she's been crushing Farming Simulator 17 on GamePass for months, and I assume this has some expanded gameplay systems for her to mess around with compared to that version. I would not be surprised at all if Farming Simulator 17 has the most playtime on my xbox out of any gamepass game, since most of the stuff I play like Halo or Gears I just run through the campaign once and it's over in like 10 hours. She has also wanted to try out Cities Skylines because she loved sim city and this seemed like a modernish take on it.
Edit: Just told her about it, and apparently there is horse riding in FS 19, whereas 17 only had breeding of cows, pigs, sheep and chickens. So she gets a new animal to breed and can ride them so shes excited. Success Sony!
