The Batman: Arkham Trilogy debuted on the platform about a year ago. Until recently, the entire collection was only available as a complete set. Gamers had to purchase Arkham Asylum, Arkham City, and Arkham Knight together in one package.
For those interested in specific titles, you'll be pleased to know that you can now buy Batman: Arkham Trilogy games individually on the eShop. The drawback is the price point. Each game - Arkham Asylum, Arkham City, and Arkham Knight - costs $24.99. Considering the original bundle typically sells for $59.99
