First thing first, let me open the umbrella for all the comments that will come, please remind this is my personal opinion and that this is my OOC opinion.
For me, who's been here since late 2020-early 2021, I've seen a masive fall from the gang scene and the gang roleplay, and for me, that's mainly because of lack of consequences, and lack of objectives to achive. In order to fix that, I will propose a series of changes that I would implement.
A) First point, consequences. Life is infinite, respawn has 0 consequences, let's go frag. People has 0 value for their life, and a quick way to fix that is to put a "cap" in how many times you can respawn in a month. You push 3 times a day for a 2 week period of time, and your character died a total of 42 times in a single month? Well, your character is gone for ever, "dead". Introduce a maximum ammount of times you can respawn withing a month, obviously with enough warnings and counters so noone "by mistake" end up deleting their character, but make it so people fear to die. And this apply for the whole server, both gangs and cops.
This link to my second point, people is not afraid to fight cos the injuries have 0 consequences. Lay in pillbox, respawn, get treated by a doctor... introduce a system of injuries that will affect your character for "X" ammount of time. You been shot in the arm? Maybe "X" minutes of shaky hands... Been shot in the leg? Maybe "X" minutes of unable to fully run....
Make it so people are still able to "fight" but think twice about the consequences.
B) Gang scene is dying and we gang members are the ones killing it. It doesn't make any sense for whitelisted gangs to fight eachother because "Y" breathed to "Z" in the wrong way, so now it is 22M compensation or war. Every and only whitelisted gangs should be holding something "unique", a item that is needed by the whole city, but that they hold the monopolio of it. Examples of it:
There is only 3 gangs in the server, 1,2,3. 1 holds coke, 2 holds powdered milk and 3 holds plastic bags. 1, 2 and 3 will be carefull with each other, because if they start an active conflict in between, they will struggle to obtain the components they need for a daily. This example don't need to be relating holding matters of the same thing (drugs, guns) but something that put a firewall to inmediate declare war over nothing; or just go on a robbing spree blacked out because, again; there is 0 consequences even if i get caught.
Non whitelisted gangs will not have this privilege, and will have to grind for it.
