One of the best games of this type I've EVER played.
Start of the story is simple. You went to help Kobold Princess, stuff happened and angry Dragon Princess destroyed the entire Kobold domain, leaving you with a lonely princess without a castle... The world is yours.
When I say the world is yours, it's pretty much is. After the intro you're thrown into a big world - that constantly grows and changes with updates - and you can basically decide it's fate.
There's a ton of princesses to choose from already and a few that are still on the way. Every princess is diffrent - and I don't mean only species - and interesting. You're the knight in this story but you don't have to be a good guy. During sieges - when the army of one princess is besiege the castle of the other - you can go in and KILL the princess of besieged castle if you really hate her or want that kind of role play.
Aside from the basic princesses you know about as leaders of their respectful reigns there are a few others hidden across the land that you can recruit. You can easily get lost in this world but in a good way. It provides many, many hours of gameplay!
Some people complain about the gameplay mechanics in form of fighting and that tutorial gives you too little... Well, if your IQ is higher than your body temperature I can assure you that in a matter of an hour you will understand it easily.
There's an entire Wikia for you! How to recruit princess, get their outfits, recruitable companions and pets among a few others things. Go there and you're golden, no problem with in-game quests at all.
You can have sex with random NPCs on the street. What's more to it? Well, the scenes aren't boring and weak CGs, they're fully animated. The slightly pixel-like look of the game is amazing. Animated scenes looks very nice so no need to worry about quality here. Lacks a bit in quantity of scenes but that will probably change.
Routes! A few of the current Princesses have their own routes that you can follow to reach the end of the game. For example, you can help your cute little Kobold Princess rebuild her kingdom and become her king and lover. Heck, you can romance a Skeleton Princess and her route makes you suicide and revive so you'll be together forever. That's just two of a few others.
There's also a conquest end where you just up and join one of the Princesses on a path to glory and domination by paving the way with skulls of other races.
You can raise kingdom lewdness so more and more people will want to have sex with knight!
And, as I'm saying it - quite a few times already - there's still more and more that I HONESTLY and WHOLEHEARTEDLY suggest that YOU try it out yourself and immersed in what is waiting for you in this world.
I was so happy with this game that I went out of my way and bought it on Steam to support the creator. Amazing game and give the highest rating without a regret about it.
