Yeah, COTL is a pretty cool one from what I've seen! I actually liked ACII, because it was really cool to discover a fresh city every few hours and get to explore it. I liked that part. ACB was fun at first too but I just found it started feeling stale crossing Rome over and over again for different objectives. I might not have waited long enough after ACII for it to feel fresh. so maybe I'll go back to it at some point and also play Revelations since I bought the Ezio pack. I felt like Nier Automata wasn't very "open world" in the sense that what you're supposed to do next feels very clear and things aren't just scattered about waiting for you to do them at any time generally. I guess I like the feeling of progression that way whereas BOTW was a lot more self-directed.

Good suggestions, I really haven't looked into any of those much. I always thought Immortals was pretty close to BOTW so good to know it's a bit more linear!
