Hi,
Had some fun creating the "perfect" character with "create-a-girl".
But then i never met the girl in a freshly created town. :(
I added her by starting a new game and doublechecked by adding the character again via "manage custaom girl", which worked perfectly and reportet that the girl and name already exists in the Town.
Guess i was just unlucky then.
My suggestion would be: that there could be a location like a railway station / bus stop / airport / harbor or similar, where you could specifically pick up player generated characters and romantically welcome them to town!
So you can be sure to meet the girl of your dreams! ;)
(Alternatively you could just make the probability of meeting player generated character very high, but imho that would be less elegant.)
regards
