A short while ago, games were dubbed and localized into whatever region that the games got ported to.
Doki Doki Panic (JPN) became Super Mario Bros 2 (USA).
Companies still make Multi 4/5/6 games which contain a variety of (european) languages. Childrens films are also often dubbed (because the kids are too young/inexperienced to read subtitles).
In those days Abe'99 was unpopular among Japan gamers.
the Sales have only picked up 3000-6000 pieces....
But in recent years Japan gamers seem to have been reevaluating overseas videogames.
Abe'99 is given the respect, much like its predecessor, of a God game or Kamige(=Godly game), that is the highest level of achievement, a masterpiece.
That's Japanese people "re-evaluating [the greatness of] overseas videogames", AlexFili, not sellers re-evaluating how much they can charge. Although if it's rare and sought after, of course they're going to charge a lot. It stands to every reason.
