Guild 01 is not your typical 3DS game. It features four games from four different game creators. Here is some gameplay footage.
In order of appearance, the above clip shows Goichi Suda's Kaihou Shoujo, American Zarigani's Rental Bukiya de Omasse, Yoot Saito's Air Porter, and Yasumi Matsuno's Crimson Shroud.
Guild 01 isn't merely a game, it's a gaming buffet.
