Shin Sakura Taisen the Animation

Anime based on Sega video games.

List of little lesser known anime closely based on or directly adapting video games, not including any visual novels or gacha. Mostly focused on JRPGs. In the case of video games with many anime, not all will be listed but will be mentioned in the notes. (In Progress)

Anime that are based within the Taisho time period. Majority are historical with a couple involving magic/ and or fantasy elements.

The Taisho era marks further Western influences in Japan from clothing to democracy. Still, the country makes a push in China, taking both island territories and areas into the North. There aren't a lot of anime set in the relatively short Taisho-era, but military motifs are almost always present.

Personally I think Gundam is pinnacle of mecha anime but since a big chunk of the series
is interconnected, I only included gundam series which are watchable as a standalone

Anime adaptions that are based on Visual Novels, and the Visual Novels have been translated to English. Also Eroge, Bishoujo Game/Galge, Otome Game, Nakige/Nukige tag.
