The problem stems from the fact that Capcom is using the "international" versions of each game. In the small print relating to the Japanese release, it is noted that "since all titles’ contents are based on the overseas versions, the titles, voicing, and text will be in English.”
This might seem like a minor issue, but it has quite far-reaching consequences, beyond the obvious fact that all of the post-match comments from the characters will be in a foreign tongue. The Street Fighter games were subject to some significant changes; for example, in Street Fighter II, M. Bison is actually called Vega in Japan, while Balrog (the boxer) is called M. Bison.
The story goes that the light-hearted reference to "Mike Tyson" was deemed a bit cheeky when it was localised for the west, forcing Capcom to switch the three "grand master" names around (the Spaniard Vega is called Balrog in Japan). Elsewhere, Street Fighter Alpha carries its western name, rather than the Japanese title Street Fighter Zero.
This might seem like a storm in a teacup, but among the dissenters is none other than PlatinumGames’ Hideki Kamiya, who has branded the collection a "quick cash grab" by Capcom.
Street Fighter 30th Anniversary Collection arrives in May 2018 on Switch, PlayStation 4, Xbox One and PC.
