There wouldn't be a season 2 because some people were saying that the mangaka has copied parts au scenes from other anime and made it into his own. So, there wouldn't be a season 2 for no game no life.
Yes I believe No Game No Life will have a season 2. Cause the movie No Game No Life Zero movie was based in a war setting in the past. Once the present came around from where season 1 left off. Sora,Shiro and the rest of the group seas standing on the edge of a cliff. And Sora alisema see wewe inayofuata game. So I do believe based off of that. NGNL season 2 might happen. Here is to hoping for it.
