Sakura Wars is such a weird thing, because I'm sure you remember as well as I do how ubiquitous it was in the mid-to-late '90s/early 2000s with all the shows/movies, video games, and other assorted merchandise. It was very heavily marketed, possibly on par with Evangelion during that same time period, but looking back now it kind of feels like it disappeared overnight.
Maybe people just grew bored with the setting? It's basically Taishō mixed with steampunk, right? I never liked the mecha designs. Pressure-cooker-ass-lookin' motherfuckers.
I'm sure I've linked to that one several times over the years. For me it will always be the perfect encapsulation of existing as a shitty little '80s kid.
