About Assassin’s Creed IV: Black Flag
Assasin's Creed IV: Black Flag is a pirate game. Being the fourth “numbered” instalment in the series, the story follows a new protagonist, Edward Kenway, who tries to build his Pirate Republic. Help legendary pirates like "Blackbeard", Charles Vane and other well-known pirates establish their empire while fighting the mystery of the Observatory - something very valuable for the Templars. Also, you will have to continue your infiltration in Abstergo and discover some new details about itself.
Although being in the Assasin's Creed series, the game provides you with some new mechanics. Giving the player full control of the ship, you will have to cross the open-world sea and fight for your piracy. Ships will be sinking, destroyed and massacred. If you prefer exploring, a whole new underwater world is ready for you with its beauty and danger lurking in the streams of Carribeans. Experience the pirate life at its best. (?) (needs a better ending)

How the Assassin’s Creed IV: Black Flag FPS estimate and refund verdict are computed
Each game is scored on a 0–9 demand tier from its published PC requirements (and a year/genre fallback when requirements are absent). The FPS estimate compares your selected GPU's relative-performance index against the tier's required index using a diminishing-returns curve, then scales for resolution. The refund verdict compares your playtime and purchase date against the platform's published window (14 days / 2 hours on Steam and Epic; discretionary on PlayStation; 14-day capped on Xbox; no-refund policy on Nintendo eShop for downloaded software) and weighs technical defects more favourably than preference changes. All outputs are planning guides — verify in-game with the built-in benchmark when available, and confirm policy with the platform before acting.
