Disclaimer: This is closer to a 4.5 than a 5, but since there's no half rating in here, it's a 5.
Disclaimer2: This is more about you being a dragon trying to reclaim his right than you being a dragon that fucks humans. If you're here for the porn expect to be sorely disappointed, especially if you play the dark fantasy mode. If you're here for the mood and setting, you're in for a great surprise.
I'd play this for the choice system alone - I finally feel like I have meaningful choices in an indie VN. Thank you to the developers.
The plot isn't particularly different nor alluring, and it's really kind of generic "evil dude picks himself back up" but you're a dragon instead. You're a young dragon whose owner got bumblasted into oblivion and you roam around trying to pick yourself back up and take back what's yours... with some other magical bullshittery happening along the way, that make for interesting focuses but are not the main point of it. The writing is very good, above average by quite a mile especially when compared to the usual drivel you read from these VNs; but the characters and the interactions as well as the freedom of choice and the impact of these is what really makes this game and makes you as a reader want to keep exploring it. There are two game modes - one with unlimited stats called "Power Fantasy" and one with normal stat progression called "Dark Fantasy" - and this is sadly part of the games main negative points.
Speaking of negative points, let's talk about them. There are two, really: Voice acting, and Sex Scenes + Game Mode.
1. Voice Acting.
The voice acting can be really hit or miss. Some of them are really fucking good, some of them are really fucking bad, and there's more that's really fucking bad than there are ones that are really fucking good, which makes it kind of a mess, really. Not all lines are voiced, and hell, not even all lines that are voiced are fully voiced! Sometimes, the line will say something, but the voice will say only half. Sometimes the voice has a tone that has nothing to do with it. Sometimes they're trying too hard, sometimes not at all. Imagine Castlevania's "WHAT IS A MAN?" with the "HAVE AT YOU!" and you've got yourself a good idea of the voice acting you'll expect here.
Also, everyone's Irish. Or at least attempting to do an Irish accent. Maybe you find that sexy. Maybe you don't.
2. Sex scenes and Game Mode (yes, in the same place).
The art changes often (the sprites don't even feel like they're related to the character in the art at times, really) and it ranges between decent to poor (in my opinion, never good). The writing in them is... fair, I guess, but isn't particularly my cup of tea. I mean, you can imagine what most of them look like, and if that's your fetish you'll fucking love it, but I personally didn't find them to my liking.
Even if that IS to your liking however, then we get to the Game Mode problems.
For you to gain strength, or for you to gain some stats, it is necessary to kill people during your encounters. This means you'll often be killing the girls that have sex scenes, and damn can they have several. You can see a girl once, and if you kill her, you gain a stat, but that's like 8 sex scenes down the drain. Honestly, this is somewhat alluring - It helps ease you into the part of thinking as the dragon protagonist, and taking choices that tend towards the egotistical and animalistic instead of trying to get yourself a human harem (because let's face it what kind of dragon would even want one of these anyway???); but if you're here for the sex scenes, the Dark Fantasy mode is not for you AT ALL. You'll lock yourself out of several girls and several scenes, and sometimes may even be forced to give out girls that you were pursuing to a group to advance other stats or get out of situations. It's not meant to be a nice experience that gives you scenes for no reason, and while I can see the allure of it - and honestly, I rather like it myself - I can easily see this being really annoying (especially because, despite liking it, I was also annoyed by having to replay the game killing off different characters to get the other scenes, and finding out which characters must stay alive simultaneously to get scenes with both, and so on so forth).
Despite these two fairly big gripes, this is one of the best VNs I've had the pleasure of finding in this website, and is a true little gem. I adore it. But if you're here for a quick and easy fap and a dragon harem, you may be best suited elsewhere.
