When I think about girls, their personality kinda blends in with their looks... Just looks are not enough for me... You could say, a girl with a better personality looks more beautiful to me as I get to know them...
And, I don't know about the best girl in general... Let me categorize...
1) Best mom... Young Lora, from Come Inside...
2) Best sister... Haley from Haley's Story... What she lacks in her looks, she more than makes up for with her personality...
3) At this point, you should have realized that I'm an incest fan...
Best younger sis... Ellie from Bad Memories...
4) Best "barely legal" girl... The daughter from My Sweet Neighbors. I'd call her my "Lolita"... You know, if I were Humbert... (kidding, I hate pedophiles)
5) Best "MILF"... Mrs. Nicole Heavens from A Mother's Love...
6) Best Redhead... A Tie between Selina from Become A Rockstar and Priscilla from Reincarnotica
7) Best Asian girl... Mei from Primal Instinct
