What video games are not demonic

That's an interesting question. And I would say that there are very few video games that are demonic in any way. Many are a waste of time, or take time away from things that might be better uses of time... but not demonic. A few might have representations of demons, or extra gore, etc... but I think that if you stay away from ones where you kill people as part of the game or have to break laws, including God's laws if that is important to you, then you should be pretty safe with video games. One that I know is safe for kids is Pokemon. There are bad guys to overcome, but no demons or devil worship. All the games have a happy ending.
