Let me see who is all on an active gang crime.
Some form of notification on the right menu if a gang crime is up for joining.
As per my other post, I realize we might not want to change it too much to avoid multi account folks, but adjust the rewards from gang crimes... Maybe if a crime hasn't been done in years, it's time to retool.
Personal crimes - in what game does the completion reward decrease when you level level that activity up? If the answer is less profit, you're being incredibly short sighted. A game that has maybe 10 people purchase items probably should think about retooling how they consider maximizing profits.
