I wonder if fungus bars will become the new Spam in GDI Blue and Yellow Zone culture. During WW2, the American canned meat was spread across the world to populations suffering food shortages thanks to American soldiers and Lend-Lease. Across the Pacific and Asia, Spam was and is very popular as a cheap, tasty, and easy to store food source and it became a respected part of local culinary cultures to this day. In Britain, Spam became a disliked symbol of wartime shortages and rationing.
In the Blue Zones, the GDI fungus bars are widely disliked and are regarded as a symbol of the constant shortages and rationing after the Third Tiberium War. Many will not forget or forgive Dr. Granger and the Brotherhood of Nod for the fungal farm tiberium sabotage incident in 2050 either. In the Yellow Zones, the fungus bars might be considered a convenient nutrient dense food source and become a symbol of GDI's increased attention to the Yellow Zones and find a permanent way into local Yellow Zone culinary cultures.
