What if every player could have a personal profile that could be carried with them no matter what server they go on.
It would store their money, kill stats, cars, guns, ammo, armor, clothes, etc.
Players can choose what stats they want recorded, for example, maybe you only want to bring your customized cars to the partyserver, but not your stats or guns.
Feel free to suggest anything you want about this idea.
I was thinking this should be for official servers only, otherwise you could make your own server, give yourself $1000000 and then join partyserver.
