Apparently it doesn't matter that the PC-98 was your best choice for computerized wargames, based on both military history and fantasy, nor do large multi-platform adventures like Illusion City, Emerald Dragon, Alshark (based in part on Binary Systems's Starflight), Star Cruiser, Rune Worth, games based on Lodoss War, &c. In addition to Falcom, companies like Telenet/Wolf Team (Yougekitai: Jashin Koumaroku, Suzaku), Right Stuff (Chilam Balam, Foresight Dolly), Glodia (Die Bahnwelt, Zavas II), Micro Cabin (Elm Knight, Xak III, Gal Act Heroism), and T&E Soft (Hydlide III, Sword World PC) all made xRPGs going into the PC-98 era. Some games went against expectation by achieving fluid movement on-screen (Brandish series, Elm Knight), others integrated elements from wargames and other genres in order to hybridize (Zavas II, Sword World PC).
I hesitate to call Falcom "barely known in the West" as of 2012, let alone this year thanks to Trails of Cold Steel II releasing on PSN. Hardy old Turbo-Grafx 16 players knew about the company and its Ys games since ages ago, with Telenet and Wold Team lagging behind.
