Black Flag came out in 2013, so this tracks.

Although, having said that, they have released at least a few interesting things since then, good games and ideas that somehow made it through their corporate nonsense (which developers have made fun of themselves, like in the present day sequences in Black Flag) and might motivate someone to hold their nose and play them regardless, like for example their charming "Indie-like" games made by small teams within their oversized studios (Rayman Legends/Origins, Grow Home/Up, Valiant Hearts, various 2D Prince of Persias, etc.), neat VR experiments (e.g. Star Trek Bridge Crew), educational modes/spin-offs based on the Assassin's Creed games that cut out all of the slop and allow users to explore these game worlds freely - and Ghost Recon Wildlands, which on one hand is a hugely expensive AAA game with all of the typical trappings, from massive production values to godawful writing, but it also has a charming amount of jank and somehow really fun power fantasy squad command gameplay - but only after removing the awful launcher and DRM that makes you feel like the company hates you for buying their games.
