Gakken Trojan Horse — LCD Action Game
The Gakken Trojan Horse was a handheld or tabletop LCD game from Gakken featuring an ancient warfare theme — one of the variety of historical and mythological settings that handheld game designers explored alongside the more common space, sports, and arcade themes. Gakken’s range of LCD games covered an unusually broad variety of subject matter, reflecting the company’s educational publishing background and its interest in providing games with more varied cultural content than the purely action-focused titles of many competitors.
