I already made most of the smaller font. I reduced it by 25% and it seem a lot more readbale now.
I am not sure about player chatting, there are several options. I would like the text to appear near the character because characters have emotes, and if the text is far then people won't notice the emotes.
I had a thought of doing something like Maple story, only the more the player is close to your character the more his chat bubble has a higher visible priority.
