Celebrity Voice Actor: Curiosly enough and unlike Tengai Makyou (who used many celebrities in the voice acting) there's only voice actress who is not a bona-fide professional one: Akiko Kuno (who voiced Ratchet Altair) who is a professional theater actress. Taking into account Ratchet is also a actress as well, she fits well in that job.
Dawson Casting: Theater plays only: Many of the actors are much older than the characters they're supposed to play. The most notorious examples are both Mayumi Tanaka (Kanna) and Kumiko Nishihara (Iris). Iris is supposed to be a little kid, but Nishihara is an adult woman and much taller than Mayumi Tanaka, who (in-universe) is supposed to be the one of the tallest women of the games.
Subverted with Etsuko Kozakura (Coquelicot): Despise the fact she's also voicing and playing a little kid, she's as short as Tanaka and is able to look as closely like Coquelicot as she looks in the games.
Dueling Dubs: Considering that ADV, Funimation and Geneon had a hand in dubs for North America with different people playing different characters (This was cut down on in the wake of So Long, My Love with the Bang Zoom dub being used).
Franchise Killer: The fifth game has seemingly killed the franchise due to its weak sales. In addition, its weak sales in North America in 2010 has apparently destroyed any hope of seeing the first four games being released in the region (although there is a group on Facebook and Twitter determined to still have the first four games released in region through digital means).
Marth Debuted in Smash Bros.: Oogami and Sakura make a bit appearance in the start of So Long, My Love. But they, alongside the rest of the Tokyo and Paris personnel (with a few exceptions like Jean Leo) appeared in various anime/OVA adaptations released outside of Japan.
Sakura and Ohgami, along with Sakura Wars 3 's leading lady Erica Fontaine, finally made a playable appearance outside of Japan in Project X Zone.
No Export for You: The fifth game was released in North America in March 2010, so far the only game in the franchise to get released outside Japan. Outside of offical Russian releases of the first two games, anyway. Most fans are cynical that the release of Sakura Wars V is anything more than a lucky fluke, and NISA's open admission that the game vastly undersold its localization costs as well as the revelation that Sony already prevented another company from translating the PSP ports of the first two games seems to suggest this will remain true.
The Other Darrin: Prevalent in the North American English dubs. Although the production companies are avoiding this as of the release of V worldwide.
What Could Have Been: Gaming news sites have reported that Sega has plans to export Sakura Taisen outside of Asia under the "Sakura Taisen World Project". Unfortunately for reasons unknown, the plans were dropped and some of the games made under the project remained in Asia only.
There were also plans for a Prequel game detailing the Kouma War, something that was touched upon in the games and given a Whole Episode Flashback in the anime adaptation. Much like the Sakura Taisen World Project, this was cancelled for unknown reasons.
