As for personalities. I expect it adds a maid with her own personality to play with? Is this more or less the case?
Edit: googling the word meaning for it is suggesting its a straight up sex scene.
The file i attached to this post is the dlc form the pastbin that looks to have the content i mentioned above.
If we took your meaning, then yes, most of DLC are essential, as they tend to add more content to gameplay.
Yes that's the case. In the game a standard three girls, have each own personality, different dialogues, different reaction and of course different voice. Same with DLC ones, they add more personalities to make your maids with. There is possibility to transfer your maids from CM3D2, but it seems it isn't possible right now with english version.
Yotogy basically mean's "sexual intercourse", but since most of the players played japanese version and japanese tend to censor not only visual but text sometimes as well, it's end up as yotogy. Basically when you go with your maids at night to have fun - it's yotogy.
The pastebin that you provide is as far as i know the most recent, so it have almost all DLC that comes for JPN version so far. I still don't know if it actually possible to use it with english version, logically it isn't.
By the way, why can I not have my maids do Night Work (i.e. sleep with customers for money)?
I already made two maids free maids. I already raised their H-stats. Doesn't seem to be any option to do so. Is it locked behind story progression?
You can't really sell your girls, it's not brothel simulator, it's more like escort service if i give analogy. Fluffy one. There is swap and client action and they open up with leveling your maids job and stats. Some event's that introduce NTR too.
