Bumblebee was a gaming wiz, if he would be allowed he would play practically forever he would, not that anyone blames him. They are responsible for keeping the technology that was a significant attribute along with trade and commerce yet they are very restricted when it comes to visiting any of the surviving Cybertronians colonies. Foreign exchange and transactions are designated on the Moons due to the fear of having a similar situation as what happened during the Age of Rust. Their kind was at risk of extinction due to the cosmic rust plague for which there wasn't a cure until nearly the end of the third civil war on their home planet. As much as he wanted to absorb more about these places that diverged in development and culture in person he grew to become very reluctant to break protocol so he generally absorbed information through cast feeds and online passages he was able to look through the Datanet. If there wasn't such concern Optimus was certain that Codexa would jump at the chance to visit the colonies just as she did when one of her investigator friends mentions a possible hidden gem or to check out a recently built special amusement building. She should often bring Optimus as well along to see experience it as well to see if he would enjoy it as well.

He does miss those days along with his mentor. Optimus does message Codexa but is generally short these days he knows she is okay and be able to tell her that he's okay, even when he still regularly deals with the disappointment he has in himself.
