Do I need to say that this is a good game? That's all you need to know. Challenging, designed to try over and over if you're bad like me, and so on. Every level is a set piece based around one single thing, which I think makes it more compatible with the sort of "hard as nails" gameplay it wants to do. So yeah, I like.
I do have a small preference for BoF3 over Bo4 (wink wink nudge nudge) but BoF4 is still one of the staples in PlayStation1 out of its visuals, and its mechanics are definitely a step up over BoF3, they built over them and made them a bit more versatile. (I just don't like Fou-Lu, and I like the classic fight against the hidden deity). Anyway! Nothing of this matters, just filling some space, love this game to pieces.
