High production values, very professional animations and renders set "Treasure of Nadia" apart immediately. The women are quite unique looking and sexy as hell (tends toward the big boobs type, but you won't care too much, it fits really well).
The fantastic animations really are the highlight, but "Treasure of Nadia" is also a passable adventure game, with some moderately-annoying grinding thrown in to make sure you can't breeze through it all in one sitting. The adventure game aspect of "Nadia" is only so-so. Kinda clunky, lagging UI too. But it's alright - a little on the boring side, as far as adventures go, considering the exciting promise of the story, it kinda drops the ball by forcing you to use cheesy mechanics like entering the same area over and over, to re-randomize the loot drops, or blocking your progress by making a character refuse to talk to you for no explicable reason until you progress the plot more elsewhere, then he will talk again even though he had nothing to do with that whole plot you did elsewhere. Goofy, clunky stuff like that abounds.
But then the next animation drops in your lap and you're just awed yet again, so you keep on playing. Recommended.
