Basing on the Mame roms, I’ve always have a doubt.
The japanese version of St has a default speed slower than the “World” version. And the japanese ia is, in my opinion, more simple, or less cheap, than the world version of St.
But why this difference?
Japan had - and has - the best scene in the whole world, the best players, and, most of all, the biggest arcade gamers audience. In order to keep the game playable (and rentable) by the majority of people, japanese St wasn’t too different from its progenitor Super Sf in terms of speed and ia. And the gamers could either choose to play, with a code, the ancient versions of their favourite characters if they didn’t like the moves modifications introduced in St.
As a consequence St was a success in Japan and it didn’t shock the players, as it made in the rest of the world: the same rest of a world that had smaller local scenes and players less skilled than the general level of the japanese audience.
I remember a lot of medium players - including myself - frustrated by the speed difference - usually set by default at Turbo 2 and not changeable - and the ia cheapness, especially having played a lot Super Sf.
Many gamers didn’t get use to the difficulty and speed of St and stopped playing. Casual gamers didn’t even try or they gave up after some matches lost in few seconds against the computer.
Then why Capcom took the decision of making a world version faster and more difficult than the japanese one?
They lost a great audience and therefore they renounced to huge potential profits: the starting point of the 2d beat’em up decline in my opinion.
Who took this economic suicidal decision? Capcom Jp or Usa? And why? Which were the aims?
At that time Capcom was the leading company in the 2d beat’em up market: they managed to ruin themselves with their own hands.
