Just finished the game for the (technically) first time, and it was AMAZING
Initially i didn't know the consequences of sending Asterion out to the valley so for some reason, even though i treated Asterion really well during my first playthrough i still got to the start of the ruthless route and i was fuckin' enraged
So then and there i deleted the game for like a day, came back to it because i got the stupidest sense of game guilt, and ended up spending the next 2 days making sure i did everything right, took me doing the Hinterlands over once to figure out the best order for me, but i did basically everything there was to do except develop Pedro and Oscar's relationship to it's fullest, i found the shed, gave the 12 a proper burial, and returned the old Tapir's skin.
Honestly at first i hated the hinterlands chapter because i thought
"are they seriously not gonna find the hotel after all that, and only the ones inside the hotel get a happy ending?"
So i was, as you could imagine, relieved when they showed up at the hotel in the last chapter, i went down the romance route with Asterion and everything turned out A OK', it felt really rewarding giving everyone a pretty satisfying ending, even Nikos and Hermes, and i'm under the impression if i had filled Luke's bar all the way i would have been able to go on a romance route with him as well, decided against it tho before the final one, didn't get to complete Asterion's project or anything other than the restaraunt screens though..
I know it might actually be pretty tedious to implement this, and it would make a lot of players' really pissed if you did but, it would be interesting if there was a way to somehow complete every project, didn't keep me up at night though, i think it's already enough that Asterion and the MC have their entire lives to complete the game's remaining objectives in canon
