Clearly an early access game, so a lot of content is still missing. However, it's a very FUN game even now, and since I bought it about a year ago, it's a very DIFFERENT game than what I bought, in a good way. The team has grown and is steadily updating with new and improved content, and they're quite dilligent about squashing bugs.
The ambitious idea behind this game is pure sandbox gold, and thus far, I see no indication the game will fall very short of its goals. Even in its current state, it's a game I sink 4-6 hours at a time into. I tend to take long breaks, usually coming back after a big content update overhaul patch, but when I do pick it up, "I think I'll play Kenshi for a bit" always turns into "Wow, I played Kenshi for that long?" It's an addictive game with an extremely promising future.
If you enjoy sandbox games, survival games or games that let you make a personal mark on the world, you'll love picking up a guy here and there from the taverns in the local towns, banding together for protection, and watching your recruits grow into hardened warriors and master builders as you carve out your own little piece of the world to call your own. I definitely recommend Kenshi for anyone who like a game that gives you freedom and rewards you for surviving in whatever way you see fit. I also recommend it for those who like to start out with nothing and eventually (a long time into the future) have to means to obtain anything they wish.
If I were to compare it to other games... It's a little bit Mount and Blade, a little bit Age of Empires, and just a tiny bit Minecraft. (Tiny bit; you get to build, but you don't get to design your buildings. You can, however, place useful constructions like beds to heal in and containers to store materials and items into these buildings however you choose.)
Do bear in mind that Kenshi is still in alpha, so it's a little barren and it does have its bugs. Also keep in mind that Kenshi isn't a game that holds your hand too much. You're plopped down in a world populated with various hostile and neutral factions, and your purpose is to survive however you can. Trade between the cities, start your own society where you mine and farm for resources to sell, or prey on starving bandits until you become bandits yourselves capable of waylaying wealthy merchants and their caravan guards.
However, what you do and how you do it is left entirely to you, so do bear in mind that at first, you might feel a bit lost and without direction. Also keep in mind that the world is a dangerous place, and you might lose quite a bit before you start to see gains. Don't be afraid to fall; just speed up the time, and there's a good chance you'll wake up. If you do, you'll be tougher than the last time. Every scar in Kenshi brings you a small step closer to being the big dog in the game.
Long story short: If you're thinking about buying Kenshi based purely on what the store page has to say about it, you'll probably be glad you bought it. It's an amibitious game that is slowly doing all it set out to do, and gives you the sense of accomplishment you'd expect. It's paced to be played for the long haul, so if you enjoy open-ended sandboxes where you reap your rewards after many long hours of effort and character growth, this is definitely a game you'll want to consider.
