Nothing in the Bible unquestionably deems video games inherently sinful. But Christians should prayerfully consider whether or not or to what degree they should play video games.

Is it okay for Christians to play video games?

The Bible never mentions video games directly, but this would fall under the “Christian freedom” category of life issues. Video games can be used in a way so that people can enjoy recreation (and even bond with family or friends).

Is it a sin to play games with sin?

In general, it is not a sin to play games that contain sins: for example, you can't say that kids who play cops and robbers are committing a sin, even if those who steal in real life do. However, it is important that you don't put yourself in the occasion of committing sin when you play videogames or anything else.
