so, here is a thought and I am not sure how useful it is. What if you set it up so the threads could check the variables and only let you through if you had the right ones? This could be an optional feature that would allow stories that weren't purely liner. You could also allow people to add or remove variables in individual threads, for example you could set a variable that is just a number and have one represent meeting a girl 2 be getting her number 3 be having a date with her and in the story you would get the option to call her if x<1 and go on a date with her if x<2 that would fix the problem with threads needing something specific (like the threads could check the breast size variable to see if an option is available) and allow people to post stories with a less linear focus (like the highschool one where you are planing a party and you want to have various people either come or not come)When I included cup size and a long list as an example I just wanted to show that there were other possible uses for immersive text, and sometimes you don't want them paired. A story could include First name, Last name and Sister's name but there's no need to fill in sister's last name. Mind control stories could use the word as a keyword to activate the mind control. A field could be the name of the company you work for, the color of your crush's hair, etc. The important part to me is that a default is there so that the reader doesn't need to fill in fields they don't want to and so the correct format for this variable is apparent to the reader.
