That would make the game more Like VCS, and how Vic Vance got his gang.
It does work out fine, But making your own gang, you have to have alot of stuff to do, even though that it may take a while, i think threw GTA4, you got to start at scratch (Like every Player has tostart in every GTA game), Then become what you call a gang leader, It may take time to finish your gang off.
I wouldn't say A-Speed-O-Meter is bad, it helps you out, to see whether your going really fast.
