This game is not a 10/10. I've just put 5 stars to combat the bias and hate the games recieving by people who haven't played it. I'd give it a 4/5 stars. The stealth isn't great (very basic, and the AI can be horrible at times) but other than these 2 things, there's nothing to fault about the game.
If you are a starwars fan it's definitely worth getting (new or old). If you're not? It's still a solid open world game with some unique mechanics.
Alot of the minigames around the world are fun, the lockpicking and hacking are unique compared to basically any other game. Nix is an adorable side companion. The open worlds are vast and expansive, and have alot of detail and hidden content packed into them (not ubisoft filler, but actual unique missions that are interesting to complete). The combat feels polished, the graphics are admittedly average at best, but the skyboxes are probably the best I've seen (dynamic wise).
The weather systems make the world have a more realistic feel, and the faction system is NEARLY but not quite, as unique as shadow of mordors nemesis system.
Overall, a good game. Don't listen to the reviews blindly hating when they obviously haven't played the game, because 40+ hours in, it's still really fun. And probably the best ubisoft game I've played.
