I really think Rockstar should add more differences to the two gender's available.
For example, statistics show that males tend to get paid more than women. So therefore, after completing jobs, males should get more money. Also, males tend to be better drivers. Therefore, males should be better drivers in game aswell. In addition to this, there are more males in the army than females. Therefore, males should have higher shooting stats. Males can also lift more than females, so they should have higher strength stats.
Statistics also show women are far better at cooking at cleaning. Therefore, in game, female characters should be better at cooking and cleaning. Also, it is a proven fact, that women are better at decorating, therefore women should get more customizable options. Also, most women use sex appeal to get stuff they want, so it should be easier for women to outrun cops and get better prices.
Thoughts? I really like my ideas.
