Most of the time I don't go with pregnancy in games, but sometimes I'll get a MILF pregnant.
I don't really get anyone other than MILFs pregnant when I do choose some sort of pregnant content.
I will do it unless it locks me out of some scenes after the girl is pregnant (In more open games). It's not really a kink of mine but I will do it as a sort of finisher
"Do you get girls pregnant in games if given the option?"
Depends on what the consequences are.
I usualy try to avoid pregnancy, unless it makes sense or is necessary for the plot to advance.
Just ignoring the born children (like in LabRats 2) keeps the game playable, but is heavily unrealistic...
