You'll never see gang in leather jackets/armor with tommy guns and wakidzashi (or how it calls...), you'll always see metal armor+sniper rifle/bazooka on encounters, same items every time, so yea... it's different game, when everyone forgetting about roleplay.
its called a wakizashi, actually its used in a pair, either with a katana or a tantō.... so... :/
Well, people aint forgetting about roleplay they just dont want to use it in terms of fighting other gangs... becouse if someone would go in with wakizashis, leather jackets, small guns the other team will almost with 100% propability walk in with combat/metal armors, sniper rifles, bazookas, miniguns.. becouse thats how you win a fight

If you are that picky about roleplay, complain about how people run all the time to get somewhere, or why no one eats/drinks/sleeps or how, well you get the point.
