Play-Asia looks like they plan on restocking Mushihime, at least the Taito Best version... the page says "Backordered, ships once restocked" which usually means they plan on getting some more in.
When they never expect anymore, it says "Out of Print / Out of Stock".
When Mushihime shows back up at P-A, I will get it ASAP. Hell, you can even pay for a copy now and they'll ship it when it's available, which means they will absolutely get more copies in, because they don't let you order games they never plan on stocking again.
$74.90 for a used copy of Ibara is insane, though... almost as bad as $69.90 for a copy of ESP Galuda... I wish Galuda would have gone into some sort of The Best program. P-A still has used Ibara, so it looks like people aren't jumping at $75 + ship.
I want Ibara, but it is REALLY hard for me to drop anything more than $30 - $35 on a shmup... I've gotten 4 or 5 now from Play-Asia, either from The Best or from their seasonal sales, and 4 or 5 from the US so it's hard to pay double that, even if it is an awesome shmup. Hell, same thing with almost everything from Japan, to be honest.
