Actually, that's wrong. There exist different numbering symbology. It just happens that "Western Arabic" is the most common worldwide and nearly universally adopted in modern times. "Roman" (I, V, X, L, C, D, M) is less used but still very widespread. There's also others like Hebrew, Cyrillic, Babylonian, ect. Some of which are very arcane and seldom used anymore.
The Japanese still occasionally use their own Chinese-derived system in verticle writing which looks like 一, 二, 三, 四... But I can't remember the last time I saw it in a video game. Probably because most text in video games is horizontal anyways.
