You don't need either to do what you want. Literally just clicking some buttons and inputting numbers. Going step by step-- create the Variable you want (Following Kiel, let's use 'TIME') Go to the button that says 'variables' and futz with that as you wish. Now, make a bunch of options (random things on the top of my head-- don't ask)--
1. Smoke weed
2. Eat turkey breast
3. Write Storygame
Now, there will be a Plus/minus sign on the options panel once you make the choices. On each choice, click the button to add or subtract TIME by whichever numbers: say 'Smoke Weed' will give you -1 time while the 'eat turkey breast' option is only -3, while 'Write Storygame' will be -5. Now, click the stop-sign by 'Smoke Weed' and select 'variable restrictions', then set it so that TIME must be between 1 and 6 to show. Do the same for the other options but with different numbers (not necessarily necessary).
Mattering on which numbers you input, you might end up that 'Write Story game' will make the option to 'eat turkey breast' disappear when you get back to that page, but 'Smoke weed' will still be there because it's only -1 TIME (apparently TIME in my example started at 6 with a limit of 0)
Dig it? I'm bad at explaining stuff but hopefully between this and Kiel you can figure it out.
