A tactical RPG published by NIS America (who publish the more well known Disgaea games, as well as Ys from Falcom), this game is being delisted at the end of the month due to the NIS America's licence to the IP expiring. As a final sale, the game is 90% off the RRP down to $6 AUD in the Australian eShop, or $4 USD in the US eShop.
There is a physical version but it is far more expensive.
The Steam version is not on sale, but is also not being delisted as it is published by Dragami Games instead.
I have a physical copy of this I purchased for $29 years ago. Now I cannot find this game anywhere.
