Horizon's Gate

Horizon's Gate is a open world turn-based RPG. You build up a fleet of ships, a crew, and commence in naval trading, naval warfare, dungeon exploration, or even advancing the main storyline if you're tired of doing your own thing.
There is a lot of content and systems in the game. Different battle systems for sea and land. A system for trading, building up smaller towns. And mainly the land combat, with about 40 different classes, each with their own passive and active abilities and weapons (or magic) they specialize in.

The problem is that, despite there actually being a lot of content - the game is easily over 40 hours long - this comes from there being a lot of different systems, and these systems don't influence each other very much. Instead of one solid 50 hour game, there are three barebones 10 hour games and one almost decent 20 hour game. Basically everything that is not the land combat is quite basic, and yet the land combat is the one that they seem to let you do the least.
But even then, the classes have the problem of being very disjoint. They form a network of dependencies where you have to train a combination of earlier classes to unlock a later class. This is fine at the start, but as the game goes on and you want to play an advanced class, you have to play a complete beginner class that does something completely different than the class you're trying to get to, just so you could unlock it. Switching away from a class makes you lose all the abilities you gained from it, sort of starting from zero each time. In that sense, it's not very exciting, and the later classes, while powerful, don't really feel like a culmination of all the progress you've made, nor do they have a whole lot of abilities to use.

Honestly, it's an impressive game in the sense of how many different things you can do, but for every single part of the game, I would rather play some other game that does that thing better. They have falled into the age-old trap of trying to do too many things and succeeding in none. If you are the type of person to like open-world RPGs with an emphasis on freedom instead of any specific gameplay feature, then this could be a good game. There are definitely a lot of people who like it. But I prefer more focused experiences, so I can't really recommend it.
