This is surprisingly good for something that doesn't even try to hide the fact it's a farming simulator. That said, of course it still *is* a farming simulator, so you *will* be doing some things that are a little more tedious than you'd expect from a typical game. For example, there's no denying that a large part of farm work is driving up and down a field at slow speed, so you will be doing some of that. At the same time you don't have most of the sources of excitement that other open world games have, you're doing honest work (except if you're stealing golf carts, which is possible and apparently nobody cares) so you're not going to be in any police chases or shootouts. The game does a very good job at simulating a farm. You start out with some money, machinery, a loan, and a field (depending on difficulty) and manage the operation from there on. You tend your fields, buy machines, buy more fields, perhaps some animals, and so on, and the level of detail is mostly pretty good. All this takes place in a completely open world, and while you can't buy any cars unless you install mods, there's a very large selection of tractors and other equipment that you can drive around. The nice thing is that equipment generally works like you'd expect it to work: Trailers can be attached to tractors, or in some cases to other trailers, making trains; then you drive them over a grate and press a key to unload your grains, which will happen in a way specific to the type of trailer you're using. Front loaders can pick up things and carry them around, sowers sow, sprayers spray, additional tanks attached to the front of your tractor provide more fertilizer for the sprayer attached to its rear, balers pick up straw and make bales, which you can then pick up with a front loader or another machine that stacks them. Cows produce manure, which you can use to fertilize your fields if you choose to do so, and so forth.
The game does try to alleviate some of the tedium by letting you hire help for some of the repetitive driving tasks. For example, plowing, cultivating, sowing, fertilizing, spraying, and harvesting can all be done by a computer controlled clone of you. This is implemented very nicely, you just drive the machine to the starting point and press H and it'll start doing what you'd expect it to do. For example, a combine harvester will start slowly harvesting your field, driving up and down, and eventually stop when it's full. Then you can pull up next to it with a trailer and the computer help will extend the combine's pipe and unload the harvest into your trailer and continue. Similarly if you drive next to it while it's harvesting, it'll transfer the harvest to your trailer as you go. This makes it very easy to do some of the typical farming tasks that normally require more than one person. It also adds an aspect of time management to the game when you have multiple computer controlled helpers working your fields and need to jump around between them to support them.
You also don't have to wait for your plants to grow. There are three settings to control how fast plants grow, and separately you can also speed up time by 120x. Machines only work at one fixed pace, though.
The farming aspect of this game includes various types of grains, potatoes, beets, as well as cattle (for dairy), sheep (for wool), and chicken (for eggs). Additionally, you can buy green houses that you can freely place on the map to grow things such as herbs or tomatoes, and you can buy bee houses that'll produce honey.
In addition to typical farming tasks, there also are some half arsed missions (basically two types: one requires you to pick up something with a front loader, another requires you to mow strangely rectangular areas where grass suddenly appeared on the golf course). You can also buy solar panels and wind energy converters, which will provide a nice consistent stream of extra income (they're a little too good).
I'm rating this game a 9 out of 10 because it's a good farming simulator with a very nice open world and very detailed equipment. But as I stated above, it's still a farming simulator, and not an action game, and I would not necessarily expect it to appeal to the same audience as other open world games.
