Upcoming games can be included too as long as you have experience with it on dmm.
I want to know how other people is enjoying with the games so far. You can either sort with your personal ratings or invidually vote them, up to you. I didnt played many nutaku games and i actually dont want to involve in this voting but gonna do it also as an example:
#1 Aigis: Only nutaku version lacks decent amount of things, otherwise its a great game for me for all aspects, be it gameplay,(undoubtedly best at it) collection and events. Tho gacha can be troublesome as nutaku version isnt generous with sc rewards or compensations like dmm. (unless you're a whale)
#2 Fkg: Has a very f2p friendly gacha, not too grindy gameplay. Would go on with it if girls had at least 2 scenes. Maybe will continue in the future.
#3 Hitsuji Chronicles: Is an interesting game, too bad that initial events was hard that i left from it so soon, also have very f2p friendly gacha which is the most important part for me but game closed at dmm side so, not a good idea to start all over again.

... (this area gonna be filled with all other games)

#?? Idol Wars Z: The only pro for me was having a good production and rekting people easily on dreamfest, other than that there were no real events when i was playing it and they were 'only' improving gacha and bringing p2w girls. Gacha is one of the worst, tho tickets were not that hard to come by. Game has a lot other issues like loading screen etc.
#? BGR: Girl designs really sucks, there is a reason why they show their upper part on main screen but not as a whole. Worst gacha system of all nutaku games for sure. Even worse than iwz. Sure they hand out rank up tickets but the amount of them is not even worth mentioning ;/
Other than these, tried some others but wasnt my type, still i've had some experience with Girls Kingdom, there are tons of similar type of games at everywhere and you dont play a H-game just for porn, it should also give you joy with gameplay part which GK lacks horribly imo, dropped so soon from that also, no idea with scenes+gacha system so im not gonna vote it.
