This was a cool start and I'll definitely look forward to having another go once there's more to it.
Interesting world building to start. But I will say I'm kinda confused from the mythological aspects (and I guess geography).
So it's all going down in Celtica and all of the people/tribes seem to have come from the "Otherworld". Now that sounds spooky and supernatural... but then they're described as coming from the west/north or whatever, not out of another dimension or anything - so that implies there's this one land that encircles Celtica and the various tribes all came from different parts of it? Kinda weird.
Then it talks about mortal life being fickle and everyone ages and dies until the last tribe that can extend their lives indefinitely (also weird to call that immortal rather than unageing, but that's a different problem though). Okay so they're not gods. But then there are gods... like the lady in the golden armour who are just chilling about completely integrated into regular life? The Morrigan I can kinda get being all spooky and whatnot... but goldenarmourlady (her name didn't register with me) is basically taking orders from regular folks, huh? I'd kinda have thought even gods that want to hang with mortals would consider themselves above them.
I liked the various branching little bits and whatnot.
Was a shame you couldn't wife up darkelf consensually, I thought maybe if you initially refused her advances till she said it wasn't about the life debt then she'd accept the offer to stay maybe. I guess perhaps she's set to return anyway but couldn't take the risk. Shame though I tend to like to treat the "bad" girls well and good girls poorly (or should it be whorely).
With Etain it seems you can "get" her if you're somewhat restrained. But I'd have liked an opportunity to mess with her while her mind was soup from the crystal and corrupt her and whatnot into serving you, rather than it just being a pump and dump. Turns out while I initially thought she was some boring lady with an 80s hair cut... give her red eyes and black lips/nails and suddenly that's my kryptonite.
Likewise it's kind of a shame you've gotta take a low-sex path to catch The Morrigan's eye, as I do like a good villainess style bad bitch.
I found it interesting when I stumbled into the carpenter class, initially I thought one of the ones on the starting screen must just have been incorrectly named, then I thought oooh secret one... then I realised it was just an early end, still a nice addition, and gets you a preggo elfwife shot.
Oh yeah, it seems the game isn't keeping track of who you nut in. Now maybe it all gets reset after the prologue - time passes everyone from before is dead and you start over or whathaveyou. But if it doesn't then it's probably better to track these things even if you think you probably won't need them... maybe you want to do a path where Etain is knocked up and you can blackmail her (into giving up that swollen belly preggo sex) because she doesn't want it revealed that the child might not be her betrothed's, etc.
Graphics aren't super fancy, but and I appreciated all the monsters and stuff feeling like they fit. Obviously work has gone into the models and stuff - like the prostitute when morphed into an enemy didn't look completely different and still was recognisable, and I'd imagine that's not so easy to do compared to just swapping it out for a rando monster asset.
