And I feel as though there should still be 2 major events to deal with in the story. We got at least 3 bads to face: Xerces, Tanurak and whoever holds Ivala. I guess we could deal with all three in one big battle, but I reckon it should take at least 2. (Plus lesser plots involving finding more shards, Zelica's fate, putting The Mother down, possibly rescuing Mithyn...) Might still be a lot of content to come. Though %-wise I suppose it's almost done.
I think we're getting one more "normal-ish" event in the next patch (the stuff with Tyna's marriage) before it starts really breaking into the real final battles, but no telling how many proper events the endgame will take, and there will probably be 1 or 2 open-world breaks in there.
I was curious about this too. I saw the patch notes mentioned which scenes got illustrations added, but there's no real context to that for people who haven't been playing for a long time. Maybe mentioning which chapter those scenes are from in the patch notes would give those of us waiting to play until it is more complete a better idea. Something like "Chapter 1: 100% illustrated. Chapter 2: 80% illustrated. Chapter 3: 10% illustrated..." might be nice too.
And before someone mentions it, I realize there is a LOT of content in the game, and not every scene is going to get one, and I'm not trying to start a flame war over how many lines or words constitutes a scene. I'm just looking for some rough estimates to get an idea of what's been done already.
I do think almost every "real" scene will get art. But anyway, the start of the art was implemented, in 3 phases:
Phase 1 was getting art for every scene in chapter 1 to appeal to potential new players, this is already done.
Phase 2 was getting art for at least 1 scene for each woman in the harem and other main characters, this is already done but the content is distributed all over the place because several characters are introduced at different parts of the game.
Phase 3 was to resume making art for scenes sequentially, this is being done now, I'd guess chapter 2 is about "25%" done.
