Original Commentary

Why are the FBAO characters talking using regular word bubbles? Not just because we're lazy, but to indicate that Brisbane and Kimberly are talking in real life. No chat or microphones this time - Terrence

Modern Commentary
Why didn't they go to social media or the FBAO subreddit or anything like that?

Firstly, none of that existed. Second, their computers aren't powerful enough to run Final Battle Adventure Online and load the FBAO messageboards at the same time. - Terrence
