"Microsoft actually asked us if we could put it out," said Maegawa. "We're thinking about it, certainly, but it's not as simple as just saying 'OK, let's put it up.'"
nope "With Ikaruga, we released it as is without having to do or add a great deal to the game, and it was popular and well accepted for what it was," he added. "But if you play Radiant Silvergun nowadays, it's certainly aged in assorted ways, and I'm not sure they're all good."
Radiant Silvergun debuted on Saturn and in arcade form in 1998. The game has not been released outside of Japan.
