I've heard about this, but I haven't checked it out. The MF Bunko label scares me.
In case you're interested about stories with video game relevance, I also suggest
僕と彼女のゲーム戦争 (Boku to Kanojo no Game Sensou) by Shiwasu Tooru. Aside from the very nice art, it's got very good reviews with its four volumes. It's like Haganai, only with games and nice art by Happou Bijin.
