I am writing this review to balance out the rather negative feedback. I have been playing NLT Media games since Visiting Aunt Sara. I have a very good picture of how the games have evolved.
The first game of this trilogy(so far) got me with its atmosphere and gameplay. I am NOT a fan of RPGM, so it was a nice surprise that quality games can be done with this engine. (without the retarded oh so hated dime a dozen chibi characters)
The second game, Treasure of Nadia refined many gameplay elements of the first title(Lust Epidemic), but unfortunately though the gameplay got better(except the ancient temple puzzles, God I hated those), I was not fond of the setting(I hate tropical or rural environment) or the ladies. With the exception of the librarian and Nadia herself and of course Madalyn most of them were rather lackluster for me, but I know that is my personal opinion, a matter of taste. Yes and the MC was a joke, typical little shit with mammoth dick. The spelunker idea was just plain stupid.
The latest installment is a nice combination of the atmosphere of the first one and the even more refined gameplay of ToN. The map is just as big as ToN and it has the atmosphere of Lust Epidemic with a very nice implemented detective/mystery solving story which hooks up with some ToN characters as well, more than ToN did with Lust Epidemic.
Plus points for the seraph as a guide(and she is more than gorgeous), I couldn't really put Evie anywhere in ToN.
The ladies are so far the best ones. I can only see 1-2 less fortunate designs, but most of them give me, that the ladies from ToN couldn't. Voice acting is rather refreshing, and has been implemented well.
All in all, I am very pleased with how this game turned out to be. Considering the negative reviews I was pleasantly surprised, hell it even exceeded my own expectations. I hope it keeps these characteristics and does not get lost and jumbled by the end as it happened with Lust Epidemic and steers away from the late game boring reverse gangbangs in ToN, which were rather redundant.
