I'm unsure whether to call Raid On Taihoku a "historical game", since it's an adventure game with enough daftness to feel a bit unlike what that phrase brings to mind. But it's set very thoroughly in Taiwan towards the end of World War II, and though the focus is a young girl's relationship with her family and friends, that context is critical to why I've enjoyed it so much.
Taxonomy aside, then, the important thing is that it's enjoyable. It hasn't hit the emotional highs of the kind of interactive fiction I favour, but for a story with such heavy themes, it provides a relaxing drip feed of mystery reveals and plot thickenings in between low-pressure minigames. It's a good time, without undermining its obvious respect for the people who had to live through this.
