Im not too sure as that info i go online, theres only one rule change id like to propose, if Gaia code is entered the Text on the menu will be red, its such a pain to restart the system everytime just to get the code on film, time should always start on when a character is picked and not when the code is entered, No runs really seem to be done with Gaia on the site so i feel it wouldnt change it much. It would be easier to sumbit runs without having to get the code on camara.
