NHK ni Youkoso!, Shoujo-tachi wa Kouya wo Mezasu Recommendations
NHK ni Youkoso! and Shoujo-tachi wa Kouya wo Mezasu both share characters who are heavily engrossed into the gaming project that they are making. Furthermore, the main characters in both shows bring out both the best and worst of each other that you wouldn't see otherwise if the show centered only around one person. What I mean by this is that, for example, some of the main characters serve as emotional support pillars. The main difference, however, is that NHK is much heavier on the drama aspect.
Both shows are about making games,and about otaku life.
