In a gamemode i mainly look for realistic they’ve managed to make it, like on most RP servers:
There about 3 gun dealers and the prices of the guns are too low, everyone ends up with guns and just rdm’s like mad. Also every single class can buy guns in one way or another which creates no business for gun dealers.
Nobody buys drugs, and if they do they buy one lot and dont touch the stuff again, it would be good if you could import it where if you try it once, you become addicted and if you dont take that certain drug again you start to become ill. This will create more business for Drug Dealers.
Money is a big part in RP and on most servers it is so easy to make, you buy a money printer and sit in a room and just collect money for fun, which is terrible, because nobody needs to work for anything and job roles just get forgotten about.
That is my input, hope it helped.
