Well, it’s definitely totally different from Stardew Valley type games. For one thing, you can’t harvest crops by swiping a finger over your screen. Instead, you need to get inside your harvester and actually drive it back and forth across the field until it is full. And it is the same with ploughing, seeding, liming, removing weeds, whatever: you have to manually do it yourself (or pay a worker to do it, of course).
That may sound like work instead of fun, and I wouldn’t blame you if that turns out to be your take on the gameplay, if you try it. But for me, it just kind of works. It’s extremely satisfying to mow a large field of grass, and then windrow the mowed grass in neat rows and pick them up with a trailer, all the while listening to a bit of music. It is slow, relaxing gameplay. I’m busy enough in real life, and most other games I play are a lot more frantic. This is my game to slow down a bit.
At the same time, it feels weirdly rewarding to be able to buy that new expensive tractor or harvester with money you earned yourself, by selling crops you have grown. Or completing a production line all the way from the chicken eggs to the cakes (haven’t done that yet, by the way).
All in all, I can’t really explain it very well. It just clicks with me, like that other slow game, Euro Truck Simulator, did a while back. You can even play Farming Simulator with a steering wheel, which is fun! It is by no means perfect. For example, the handling of vehicles on the roads is rubbish. But that isn’t a problem: most of the time you’ll be creating straight(ish), fresh lines on fields anyway, not on the road, and the driving works fine there.
I’d say: try it out. Perhaps even with an older (cheaper) version. The basic gameplay hasn’t changed much over the years, so if you hate FS 15 (the one I started with), you’ll hate FS 22 just as much. If you like 15 however, you’ll love 22!
