True. But the risque move paid off?
For Phantasy Star IV's case yes, but generally 16-bit RPG on western didn't sell as well as sport titles (in US) or platformers (in Europe).
After few years passes (in 32-bit era) then western gamers have started to notice RPG's charms while their 16-bit sport titles have aged badly.
Perhaps, if they're going to re-release the Sega Genesis Mini as well as other miniature consoles... But what about PC players?
It's just a speculation, there are many other speculations too.
May be SEGA of Japan are preparing SEGA® Mega Drive Classics™, SEGA® Saturn Classics™, and SEGA® Dreamcast Classics™ for all system with different developer.
Did you know that SEGA® Mega Drive Classics™ were only released in western, not in Japan?
