Rating something at a 0.1 stage would normally feel a little strange, but I don't see any reason to wait. Caribdis more than proved their storytelling and design credentials on OIAL...and Eternum is dialing everything up to 10. The visuals are top notch, the story hooks you immediately, the humor might not be for everybody, but it's definitely for me.
Would I like a wincest code after how well it was executed in OIAL, I mean, sure. But it's hardly a deal breaker when the game is on this level of quality.
I'll come back and add more detail after I've played more chapters...but it's hard to imagine this game doing anything but getting better and better.
Cheers to the creator for your hard work!
Update - post 0.4
Well, that's the danger of getting caught up in hype...I put the cart before the horse. Caribdis is still a good storyteller, and you can still see the hard work and effort that he puts into his work in his games. They are polished and beautiful.
But the story is really struggling. In OiAL, whether you like wincest or not, it provided an early pathos with the various character interactions. This game doesn't have that yet, and despite some promising humor, it's not clicking all that well. The stakes also feel a little arbitrary and un-pressing...and the greater overall plot is too reminiscent of a certain book/movie combo I'm sure many are familiar with.
Also, the VR world of Eternum is rife with potential to use the imagination and explore unique and unsual kinks and storytelling points. So far instead it has plunged from one generic trope into another.
As of 0.4, I wouldn't say Eternum is doing anything poorly...but it's not doing anything exceptionally well either.
