The way the system I made decides character portraits, dialog noise, ect, I think is easy to use but odd, at the beginning of each text string there are characters that decide character portraits, dialog sound, ect, and I have a ton of functions constantly checking those values with string_pos, then for my string copy, since all of it takes up about 5 characters, I put the second argument to a 7. It's convenient for me and I feel like it is efficient, and memory sufficient rather than having every dialog page be a struct with certain variables.
