Positives:
- Big open world (albeit one where you have to follow particular paths instead of exploring anywhere) with varied terrains and lots of different courses to run.
- Ability to own and care for lots of horses.
- Horses have stats, personalities and "quirks". Their negative traits can be trained out. Lots of different coat colours. Horses do feel unique and there are in-game benefits to switching it up between your horses.
- You can catch wild horses and breed foals. There is a genetics system for breeding which is fun.
- Varied care mini-games including grooming, washing, feeding and petting.
- Ability to build and upgrade your ranch, and additional ranches around the open world site, makes for a fun addition. The game incentivises exploration by having you collect the resources you need to build up your ranch around different points in the world.
- Lots of customisation options for your buildings, horses and avatar.
- Plenty to do after you finish the main story.

Downsides:
- The camera jumping is awful. Borderline unplayable at points because of the motion sickness from the camera jumping about, especially when mounting/dismounting, which you have to do a lot to collect certain resources.
- As others have mentioned, the main story is very short and doesn't have an especially satisfying conclusion.
- Unless you buy DLC, there is only one horse breed. With DLC there is 3. This is frankly unacceptable, especially in a game which emphasises variety of horses.
- The whole game feels unfinished. It feels like the devs had ambition to begin with, but for some reason just had to... stop. Parts of the game feel ambitious and cool. Other parts feel very much like "oh... is that it?"
- Lots of visual glitches.
- Not enough fast travel across a big open world which isn't that exciting to ride around in, to be honest. You have to stick to the set paths, which are long, and during the story you will have to back and forth across the same paths a lot on various fetch quests. It's especially frustrating getting your horse groomed and washed ready for a race, then having to spend ages crossing the map to get there, and by the time you've got there your horse is dirty again with no ability to clean them apart from back at your ranch.
- Not a lot of incentives to complete races, especially when you spend ages to hit the top spot only to be knocked off it by AI literally the next in-game day.

Overall: the breeding and ranch management system makes for a fun variant within the horse game genre, but overall this is an unfinished product which leaves you feeling disappointed. Companies pitching games at girls need to do better. Games pitched at male audiences manage much better horse mechanics as a minor feature of a bigger game than games like this which are supposed to be all about horses (seriously, if you want a good horse game, play RDR2).
