I'll pass on a game that treats women like objects to be desired and attained rather than DA, which treats them like people
Lovely comment. Perhaps you are also going tell me that all women prostitutes are special snowflakes that have been oppressed ? 
Women are not objects, no matter how much you want it to be true. Women are individuals who make their own choices. Women have agency, they are not perpetual victims.
A woman who chooses to be a prostitute is not oppressed or suddenly becomes just an object to be attained. A consensual prostitute is just a woman engaging in a business transaction where she exchanges sex willingly for resources which in this case is money. She is, in this regard, no different from a blacksmith or a herbalist or an enchanter or a general goods trader.
So far in The Witcher series, the prostitutes that the main character, Geralt, have come across and have the pleasure of having sexual intercourse with, do not in any way, seem to be forced to be there. This is no different than prostitutes in countries like Germany and Australia, where they willingly ply their trade.
Furthermore, women who willingly become prostitutes in this fashion are actually recognized by some degree as workers and therefore actually treated as such instead of slutty women or lesser women or trashy women.
Additionally, what does "treated like people" mean ?
Morrigan puts it very nicely:- "In my experience, everyone pays for sex." I love that woman. 
Everyone. When you enter into a romantic relationship with another person, one of the goals is to have sex with this said person. To that end you court them, you buy them gifts, you spend your time with them, you be emotionally vulnerable to them, etc. One of the goals of this is to engage in sexual intercourse and to that end you are investing your resources which are your money, your time and your emotions into the relationship.
When a person has sex with a prostitute willingly, the fundamental dynamic remain the same. One gives a way money for sex while the other receives money in return for sex.
Does this mean having sex with a prostitute in a consensual manner equates to objectification, oppression and treating others as lesser beings ? No. It is a different path for a person to gain access to sex and resources. It is not a worse path or a better path or morally superior path. It is a different path. A more streamlined, more business-like, more direct path.
This is why CDPR's depiction of prostitutes are, again, better. The prostitutes in The Witcher series are plying their trade in a consensual manner and there is an adult scene when Geralt access their services. Overall, it is depicted in a way mature and understanding adults would depict prostitution.
If anything, the statement you made shows that you have very limited view on sex, you do not view women as beings capable of acting on their own volition and you think of people who are willing to act in a more business-like and direct fashion as lesser peoples or even non-peoples.
It is a statement full of ignorance and naivety, signifying lack of mature thinking.
