I'm being a bit of a nerd and trying to place where exactly on the timeline this game occurs. I played through Yasui's route again (after purchasing and supporting the dev on Steam)- It's still probably my favourite NTR route of all time. I just wish we saaw a bit more corruption/it was longer, especially knowing that the dev spends time on these... Less popular bulls.
Alas, that's the point of the game. Back to the main point, the timeline seems to be:
Scars of Summer After Prologue - A year before the first game.
Scars of Summer Introduction
Now, after this point, each route chooses where it continues on from:
Yasui: After their first time having sex in the love hotel.
Nobaru: After losing all three marbles.
Vagrant: Ryoka not coming to the seaside camp and instead choosing to spend the weekend with the vagrant.
Daisuke: Unclear, but at least after their first sex scene.
To break it down clearly- Scars of Summer After seems to be an expanded remake whilst skipping the original stages of corruption. We don't know what the other paths will start at- But it's fair to assume they'll begin with Ryoka having had sex with the antagonist once.
This means the original game is pretty much necessary playing, as the game suggests. Thankfully, I think what this also means is that the entire game will flesh out Ryoka's corruption for every path- Something which I think was very much needed in some of the paths. I did feel like a lot of the time, just as it was getting good, we'd run out of events and just speedrun to the last day.
Instead, Scars of Summer After seems to be built that each day gives a new and unique event. I also wonder how/what the dev will do with the entire concept of the game. There's no 'saving Ryoka' now. No memories, no end goal of fending off the NTR villains whilst we grind stats and money. Would be interesting to see if he just reverts to a linear corruption path or if we're able to still interfere and attempt to stop Ryoka from being ruined.
Either way, very excited for the game to come out. Will be hard to wait around for the English translation...
