Both of them are kind of light hearted with some interesting action/adventure that pulls you in. In both the MC is OP and things tend to work in their favor. They both share the whole "empire building" aspect. Reikenzan has a stronger focus on magic and training, while No Game No Life focuses more on having fun and playing games to conqure the world
