A freelance artist has managed to build a gorgeous, anime-fied recreation of Tokyo in Unreal Engine 5, and you can play the free demo now.
Yan Ru's Anime Tokyo presents Japan's capital city as we've seen it in countless an anime, and plenty of video games too, just on a much bigger scale. Just off the top of my head, Persona 5 lets you explore a limited number of districts in Tokyo, while the Yakuza series largely takes place in a fictionalized version of Shibuya - called Kamurocho in Ryu Ga Gotoku's absurdist crime drama series - and Akiba's Trip is all about the glorious anime district of Akihabara. But as far as I'm aware, there isn't a game where you can explore the entirety of Tokyo seamlessly - certainly not in Unreal Engine 5 - and that's what makes this tech demo such a novelty.
