It ' s like you are looking to get a Ferrari that is not Ferrari . If by Gunpla you mean plastic modeling then there are a whole lot of stuff to look into . You can build cars , motorcycles , fighter jets , airplanes , trains , etc . If you want to do mechs then there are Frame Arms , Macross , Evangelion , etc . However , most mecha models are based off of something whether it ' s anime or movies . The term Gunpla almost always reserved for Gundam Plastic model kits . I know several guys who build Gunpla but don ' t watch the anime . They still enjoy the hobby . However , when you engage in conversation with other builders , you may find yourself being lost and don ' t get all the references . To watch some or not , it ' s your choice but you can always enjoy building .
