I'm going to call my bf out on his gaming habits
I'm not sure why you would want to call him out?
I want him to change and become a better person.
You should communicate your needs with your partner. It might backfire on you if they do not want to give up gaming.
It's fine if my bf can't play as much as I want him to. I will find a way to enforce my rules.
While speaking with him about it is fine, you should enforce your rules on someone that you love. You need to accept them for their faults, and speak with him about what is upsetting you in hopes that he will stop.
