Wow, ok. For me, it's quite the opposite tbh. When I started playing Eternum, I just imagined the potential this game has. Anything is possible! I was surprised by how much the game actually turned out to play in the real world.
The only problem I'm seeing is that Eternum does a lot of things and provides great variety but it does none of those things as good as a dedicated work. My main example is the heist: It was a cool segment, but it didn't really capture the thrill of a good heist movie imo.
But it makes sense, I can't expect Cari to be a master of writing in every conceivable genre. He is trying his hardest though, and his results are still very impressive, he's still a legend in my eyes.
Coming back to your critique: I can't really relate to your experience. It seems like what you dislike is not the game per se, but its central idea. To you, there sometimes can be too much variety. -- But I'm guessing at this point. Feel free to elaborate if you want to.
