Truthfully there's no game like Eternum. The level of production and quality is shocking. Even in pay-to-play porn games, the plot and characters are never this good. I enjoyed Desert Stalker and Knightly Passions, but both either lack the quality of design or quality of intimate scenes, Eternum nails both, all while keeping an amazing narrative like you said. Genuinely hyped for the future of the game, and more of my thoughts are available right above your comment.
"Realer than real"... I think means more than meets the eye. We will see!
