This is a true throwback to the older games mixing in more and improved features I wished were there originally.
Thankfully this isn't an Assassin's Creed game in name only; like the last 3. Granted the story isn't long but my theory is Ubisoft have dropped this as a test for future AC titles.
For the first time since AC Unity I am enjoying an AC game, thank christ the stupid as RPG items have been removed and it is back to being a primarily stealth game.
