There's An Official Food Wars 3DS Game Coming Out
...Unfortunately, all we have is a brief trailer to show for it.
Food Wars: Shokugeki no Soma is a pretty interesting shonen anime series that revolves around cooking and a special protagonist who can make pretty much any dish imaginable. It's a cooking show at heart with familiar anime elements and some very elaborate scenes showing off the dishes created. With that in mind, it's hard to imagine what kind of 3DS title could be made from these thematic elements.
Food Wars: Shokugeki no Soma: The Dish of Friendship is an upcoming handheld title from FuRyu, and the company has just released an official non-gameplay trailer hyping the game up. There's no real information included in the trailer, but we can surmise that it'll probably include cooking segments in some way, shape, or form. Perhaps it'll go the way of Senran Kagura: Bon Appetit and feature several food-based minigames that make sense in the context of the show.
Time will tell, and we'll get you more details as they arise.
