I think that Horizon Forbidden West is worth it for a vast majority of players. Though I might have come off rather negative, I enjoyed the game quite a bit. The time with Aloy and the Forbidden West was much more fun and intriguing than the first game. In the end, though, it comes down to you. If you liked Horizon Zero Dawn, there is seriously no reason that you should not play this game. It is a much better experience overall and will be absolutely worth your time. If you were like me and did not love Zero Dawn, it could be worth a try at least. I think you should watch some gameplay videos to see how the combat is before picking whether to pick it up. But if the idea of a better open world format has you interested enough, then I think you should go for it.
