So as we all know, San Andreas is rather empty at the moment as a whole on SAES - the decreasing server populating and etc, etc. Now, I'd like to suggest the follow, that we close off the available map on SAES, similar to how it is when you start GTA SA as CJ in the vanilla game.
If all the players were only restricted to either LS, SF or LV it may help to reinvigorate the community as you won't end up with the huge expanses of emptiness in the map as it currently it right now. Now you may not all agree with me, but it may be far more enjoyable to have everyone on SAES restricted to Los Santos for example. As a criminal, you would be far more inclined to seek privacy in alleyways or in a bike park; as a cop, you could turn any corner and see far more people driving down the street or walking about. Additionally, the concentration of players will mean that it may help the roleplay scene on SAES a little bit as you likelihood of encountering a player who isn't simply afk at LV X would be far higher.
I'm not saying that SA is completely deserted, all I am simply saying is that if all the players were in a smaller area, it may be far more exciting and unpredictable to play as you will encounter more people and the city will be far more customised to the community as all the organisations will have to move in.
In order to do this, I would simply recommend that barriers are placed on the bridges between the states and that all the markers/ events are removed from the states that won't be in use. Therefore, they'd still be accessible if say DE and CLO wanted to go have an 'urban war', or if someone wants to have a shady meeting in the desert or woods for example.
Feel free to add any suggestions below or to discuss the idea! (Sorry about the messed up poll - I don't know how to edit it).
