I love the map design of this game with its interconnectivity and am sad it hasn't really been done to this degree again since, in this franchise. It's a fantastic game, but it does lose a bit of steam about halfway through. The DLC more than makes up for it though, and I would recommend playing it as it has some very fun boss fights!
The switch port is very good, despite the 30 fps lock, it's pretty stable. More than I can say for the original PS3 version. The only thing that kinda smells is the sound quality, to this day don't understand why they compressed it so much.
