I agree, this one allows me to enjoy all the adult stuff with out a majorly depressing feeling from doing so.
You should try Project Myriam, and the dev does monthly updates
I mean maybe a little Guilt, but not like I get from some of the NTR stuff. ( This one is just fun in most all respects.)
So far for me the Office wife, and this one, and maybe Lidas Adventures Are some of the more jovial Characters to play. For Me
Though they each have there share of Evil bad people to deal with, there not just totally depressing over all.
EDIT >>> Should also add in there Bawdy Traditions Another fun one that is not totally depressing overall.
