There really isn't a usual sentence. It is usually based on the amount of the crime, i.e. did he do this with one video game, or does he do this to make his living? Your brother should really consult with an attorney as this crime could have some serious consequences, especially if he has a past criminal history.
If you have any questions or would like a free consultation, please feel free to call me.
These cases can be resolved without having a conviction. Your brother should consult with an attorney immediately. Best of luck. Feel free to contact me if you would like to discuss this matter further. My office number is 310.247.8230. Best. AZ
