I think it would be cool if you made Graal Era more about Cops vs Gangsters. When someone opens graal for the first time it should ask them if they want to be a cop or gangster. If you would like to change sides it would cost $1000. You could then add different levels of both cops and gangsters.
Example (If a cop kills a gangster he gets xp. If a cop kills another cop he loses xp. Almost like it is now except it stops at 0.) I think an update like this would make the game more cop vs gangster.
