Theoretically, you could use text files (like shown here) to add more comments as they are created. I coded a software to create a text file for the last ~3000 comments. You could filter it out to certain commenters, which would filter out users that don't comment as much. You could take one item out of the shown list and create an engine to spell out the comment using premade letters and characters (to match your font already made). This leaves the game and look essentially unchanged, but adds an almost unlimited number of comments. Just an idea.
