Much of Rogue is a reskin of Black Flag, including the sailing gameplay, which is still good, but not as fun the 2nd time around. The main draw is tied to the protagonist, Shay Cormac, who finds himself alienated from the Assassins and defects to the Templar Order, becoming a ruthless Assassin hunter. This adds a new dynamic to gameplay as you can be ambushed by Assassins sent to kill Shay, or you can use your training to ambush them in turn. The story mainly serves to bridge the gap between Black Flag and III so some fun characters from both get to show up and have a last moment in the spotlight. Rather than a larger overworld like in Black Flag, the world is split into New York, the northern seas around North America and the inner Riverlands on the American coasts; the first is a traditional free-running city, and the 2nd is more akin to Black Flag's sailing, while the riverlands are an awkward blend of both - that is a fine descriptor of Rogue in general. It's without a doubt a good entry, but a bit of an awkward interstitial one.
