I'm just curious, really. For reference, in D&D, STR is called Kinryoku (筋力) and DEX is Binshouryoku / Binshōryoku (敏捷力); while in CoC, STR is also called Kinryoku (筋力) likewise, and DEX is Binshousei / Binshōsei (敏捷性), etc.
Oh, and what about Ryu as a currency? Is it perhaps supposed to be a fictional version of the original Ryou / Ryō (両)?
