I saw a 一覧 of アニメ for 2013 and saw Diabolik Lovers. It sounded interesting so I looked it up and the first 2 episodes had already aired. But until then I hadn't heard of it nor had a seen anything about the game. Glad I looked it up though.
I saw a lot of posts for it on tumblr, so I decided to take a look and watch it. I enjoyed the anime, but i felt like a lot of parts of it were missing and i wasn't completely satisfied, and that's when i played the games. So happy i did! The games were much もっと見る enjoyable and told a better story than the アニメ did (in my opinion)
