I feel like simply removing the CG section and Sound Mode of the extras Mode is a very awkward way to make a distinction between a 'standard' and 'deluxe' version of a VN, especially if they're already considered to be normally included in any VN. I totally agree with Nosebleed that it would seem strange to have a large enough price difference between the two versions to justify the troubles of making two distinct versions with the options of DLCs. Of course we can't draw any concrete conclusions before actual prices are released, as those would be the deciding factor in justification.
I do like the idea of making these games more modular. Being able to buy a stripped down version of a game, especially if you're not sure whether or not you'll enjoy it is nice. However it's easy to see this separation of content as a money grab which is honestly kind of frightening. Also I think that phrasing the full game as 'deluxe' is slightly misleading because in reality it's just what would normally be offered.
As for the All-Ages aspect, it's to be expected considering KS and Steam rules. In my opinion the h-scenes weren't super important or outstanding in general. We'll have to wait and see how FW handles the whole scene that's integral to the story and Kenichi. Hopefully they don't just give an awkward roundabout description of the actual scene and instead find an interesting way to resolve the issue.
I'm happy that this game is getting an official localization. Whether or not the localization is successful depends on how FW connects to the fans and adresses their concerns. Also, the pricing of all the parts will be important.
