Dramatic Road: the origin of wind Game Review

Oct 12, 12:00 games

Dramatic Road isn't just a modern-day Fire Emblem. It's specifically a high school delinquent saga inspired by classics like Bari Bari Densetsu. ― Dramatic Road: the origin of wind has a brilliant high concept: it's a Fire Emblem-style strategy RPG set in modern-day Kanagawa rather than medieval times. Every archetype you remember from those games is therefore remixed. Archers are tennis players; arm...

But the strange metamorphosis of storytelling can always ...

Yuzu seems passive, but she's really a survivor stumbling her way into the light. ― The Cinderella fairy tale often draws knee-jerk reactions about passive heroines. Even some of her arguably more passive fairy tale sisters, like Snow White or Sleeping Beauty, are afforded more grace than the woman who rises from the ashes to become a princess. She's painted as the ultimate in passivity, a girl who w...

Dragon Quest Heroes: Torneko's Mystery Dungeon - Classic HD Switch 2 Review

Torneko's Mystery Dungeon is not a game that is a roguelike; it is a game that is like Rogue - and that distinction is more than mere semantics. ― Dragon Quest Heroes: Torneko's Mystery Dungeon - Classic HD is a great classic game held back by curiosities surrounding its release. The facts of the matter are quite simple. This is a rerelease of the 1993 original, the first time it has been released in...
