To give credit where it's due, Ubisoft has just added Steam achievements for games we'd long lost hope of ever seeing updated, with both Assassin's Creed 4: Black Flag and Assassin's Creed Unity finally getting the achievement treatment 11 and 10 years after their respective releases.

On Steam, both the recent and all-time reviews for Assassin's Creed IV Black Flag are very positive, with a total positive rating of 88%. Although Assassin's Creed Unity falls behind a little bit, it still sports fairly respectable numbers, scoring mostly positive (78%) ratings on both fields.
