Currently in the mid 20s on v0.43.1 Princess -
I should probably start by saying that I don't generally like RPGM games, for a lot of the same criticisms I have with this game specifically. So I'll break it up into story/content and mechanics.
Story - Well written, though the MC wavers quite a bit between villain and hero and you sometimes can't really predict which one it's going to be in any given situation. Sometimes he has no problem talking women into his harem consensually, sometimes it's just straight up kidnapping and rape. The MC never really seems to suffer any consequences for most of it, some of which is really brazen, which I suppose I can only handwave away as being 'kidnapping and sex slavery must just be really common in this world, nothing to get worked up about'. The other characters are all fairly consistent though and have unique personalities, which is good when you're getting into the dozens of characters. The quests and storylines seem as good as a 'normal' RPG.
The sex scenes are still mostly low-detail, but I know how hard getting real artwork is, and the writing helps. Everything's clearly had a lot of work put into it.
I'd probably score it at 4.5/5 on the content, with half off for the inconsistent direction of the MC - I don't mind playing games as the villain, but I like that to be consistent both in how the character acts and in how the world reacts to them - at the point where I'm currently at in the game, women should probably be running and hiding whenever the MC comes into town, given his track record. A similar game, Overwhored, had a similar complaint from me in that the game starts to lose sight of whether the MC is bad or good as the game goes on.
Mechanics - This is where the game gets really frustrating for me, and why I almost always avoid RPGM games in general. The game gets lost in RPG bullshit and doesn't spend enough time thinking 'does this make for fun gameplay?' I'll just list off a few things:
1. Using the wiki walkthrough is essentially mandatory. Sure, some things could be figured out with some hard work and effort, but some things are just completely breadcrumb-less. For example, there's one entire plotline that gets kicked off by going to talk to a character sitting in a bar, who you have no reason to talk to. There's like ten different bars in the game, hundreds of background characters, and this character is one you can talk to earlier on and who doesn't have a quest for you then. Who is going on around talking to every background character every five levels just in case they have something new for you? The game does have something of a mail system which it uses sometimes, although the letters just show up in random spots so even then you might not even notice you got something.
2. I'm now at 26 harem members and the affection system is getting out of control. To get character bonuses and 'love quests' you need to do things like give them gifts every day, but the harem characters are scattered across almost a dozen different buildings. Doing a daily cycle of gifts requires dozens of screen transitions. Two of the characters can wander between seven different areas that you need to hunt in to find them. There really needs to be something like a gift dropbox at each person's room, and a mailbox for distant characters with you only needing to actually go and find them when there's something to be said. There's also a furniture affection system, which I understand is currently in progress, but this is another thing that requires 100% knowledge from the wiki, there's nothing in the game providing the info you need here to get the bonuses out of it. In any case by time you can afford to spend your money on that stuff you're probably past worrying about it.
3. Quest Grind - My kingdom for a savepoint. These quests can go on very, very long with no savepoints to be found, it's almost like they included them early on to get the savepoint tutorial in, and then figured they were done with savepoints. This is kinda fucked for two reasons - first off, dying to a boss and facing the fact that you now have to do the entire quest over again only results in ragequits. Second, I have to block off a whole chunk of my schedule before doing any quests because I have no idea how long I'm going to be stuck at my computer. It's also a huge motivation to not try anything until you've overleveled it, because taking on a 'challenging' quest is too likely to just result in being a gigantic waste of time.
The actual combat seems fine enough I suppose, though the above point means I'm discouraged from experimenting much with my party makeup. After all, don't want to get halfway through a quest only to realize my team's a bad fit.
On mechanics I'd give the game a 2/5, with it kind of feeling like a punishment you have to endure to continue with the story rather than something fun in and of itself.
I'll probably play out the rest of the current content and keep an eye on future updates, but it's not really encouraging me to spend more time with other RPGM games.
