Handled via BackerKit on Kickstarter:
The Fruits of Grisaia, The Labyrinth of Grisaia & The Eden of Grisaia physical copies - $120 via main pledge
Idol Mahou Shoujo Chiruchiru ☆ Michiru physical copy - $40 via extra pledge
The Eroge version of The Grisaia Trilogy, digital only - $40 via extra pledge
I played it safe and went with this route. They removed the option to have physical copies of the All Ages and digital copies of the Eroge versions in one purchase at the extra pledge section which annoyed me. But I went with this route and basically spent as much as I would on an Aniplex set for instance. Heck this is basically 4 games here which will be more expensive at official release so I'm fine with it for now.
And for those wondering, Denpasoft will NOT be releasing a physical copy of the Eroge versions. See, this is what is pissing me off with this whole kickstarter. Both Denpasoft and Sekai Project basically shunned everyone who wanted information about this version and left it till the kickstarter ended then explain bits and bobs about it. I know the licenses are different but there was no need to ignore the amount of demand over the Eroge version. Oh well, it doesn't matter anymore.
The Fruits of Grisaia is getting released first in May followed by the others later in the year.
Note: If you have yet to fill the BackerKit survey for this kickstarter, it will close on Monday.
