Thinking about meaning of life... both series are about this. Also there is a little romance and comedy. NHK is more mysterious, but Yahari is more complicated

There are some similarities like: - about creating games (and many problems) - similar characters (tomoya-yamazaki) - both of them contain romance and humour The difference is that NHK isn't just about games like Saenai.
